Lesson Objectives: Does increasing the temperature, increase or decrease the rate of reaction (How fast the reaction happens)?
Increasing the temperature of a solvent gives the particles more energy, this in turn speeds up the movement of the particles. This increase cause more solvent particles to collide into the solute. As a result, solute particles break loose and dissolve faster.
A solvent dissolves a solute resulting in a solution.
What is the role of the Solvent in the reaction?
…………………………………………………………………………………………………………………………………………………………….

What is resulting mixture called?
…………………………………………………………………………………………………………………………………………………………….

Identify the Solvent
…………………………………………………………………………………………………………………………………………………………….
Hydrochloric Acid (HCl) Calcium Carbonate (CaCo3) Water (H2O)

Identify the Solute ……………………………………………………………………………………………………………………………………………………………. Hydrochloric Acid (HCl) Calcium Carbonate (CaCo3) Water (H2O)

What do you think happens to the speed at which the solvent particles move as they are heated up? Faster Slower No change
…………………………………………………………………………………………………………………………………………………………….
Do you think the solvent particles are more or less likely to collide with the solute? More Less No change
Do you think the rate of dissolution (dissolving) of the solute particles will more or less quickly? More Less No change
What effect will this have on the rate of reaction? Faster Slower No change

Essay On Rate Of Reaction

Rates of reaction The rate of a reaction is measured as either the amount of reactant used up in a given time or the amount of product formed in a given time. In order for a reaction to occur, the particles must collide. If more collisions can be made to take place in a given time, the rate of the reaction will increase. Some collisions don’t lead to a reaction taking place. Only collisions with sufficient energy can lead to a successful reaction. So, if we can increase the success rate of the…

Rates of Reactions Essay

Aim(s): The aim of this experiment is to find out how different variables affect the rate at which the reaction between Marble chips (CaCO ) and Hydrochloric acid (HCl) takes place. There are many variables that affect the rate of this reaction such as the following: 1. Temperature 2. Concentration (Pressure for gases) 3. Catalyst 4. Surface area Materials: 5.00 g of Marble chips 2M HCl 1M HCl Balance pan Weight scale 200ml conical flask Residue container 50ml beaker Timer/ stop watch…

area affecting the reaction rate Introduction In this experiment calsium carbonate (CaCO3) will be put into a flask and then mixed with Hydrochloric Acid (HCl). The reaction is: CaCO3(s) + 2HCl(l) --> CaCl2(aq) + H2O(l) + CO2(g) The purpose of the experiment is to determine whether or not increasing surface area of marble chips will increase the reaction rate. Reaction rate is a way of measuring how fast the reaction takes place. So the higher the reaction rate the faster the reaction takes place and…

collide in order to react and the frequency of collision determines the rate of the reaction therefore, the greater the frequency collisions the faster the rate of reaction. Particles must collide in a minimum energy in order to react and we call this the activation energy. On a low temperature particles don’t have very kinetic energy and move slowly this means the collisions are less frequency and have a lower energy so the reaction will be slow. On a high temperature particles have more energy and move…

rate of reaction coursework Essay

The topic we are investigating is the rate of reaction. A rate of reaction simply means how fast or slow a reaction takes place. For a reaction to take place the molecules need a sufficient about of energy for collisions to happen. There are ways in which affect the time of the reaction, such as surface area, Temperature, concentration and the use of a catalyst. Firstly surface area, this can affect the time of a reaction to take place due to how much exposed are it has. Temperature is another…

Lab Report On Rate Of Reaction

Science Assignment Introduction: When two or more molecules interact there is a reaction which causes the molecules to change. To make new molecules, the bonds between atoms are broken and created to make them. When the products change and reactant this is called Rate of reaction. Many factors contribute to rate of reaction being affected. For example, the nature of the reactants, the particle size of the reactants, the concentration of the reactants, the pressure of gaseous reactants, the temperature…

affect the rate of a chemical reaction: • Concentration • Temperature • Gas pressure • Catalyst • Surface area of particles (1) Rates of reaction: How quickly a reaction happens is called the rate of reaction. Chemical reactions take place when two or more chemicals react with one another by colliding with each other. The increase in temperature increases the amount of collisions between particles, this fastens the reaction. If a reaction has a low rate that means…

Essay on 7 Kinetics Rate Of Reaction

2014 #7 Kinetics: Rate of Reactions Lab The purpose of preforming the Rate of Reactions lab is to observe the reaction and reaction rate of CaCO3 and HCl at several different concentrations, then also to change one variable of the lab to see if the results from the change test differs from previous tests. A reaction flask was set up to monitor the rate of reaction between calcium carbonate, and the highly acidic hydrochloric acid. The method of determining the rate of the reaction itself was to place…
