5a) As you increase surface area, more reactant particles are near each other (not changing Kinetic Energy profile of the reactant particles just more particles per KE now) so there will be more reactant particles with the activation energy or greater causing more Effective Collisions (EC) increase the rate of products are made (#priducts/time) called increase Rate of Reaction. |
5b) Decreasing the temperature means that some energy was removed from each reactant particles. So some reactant particles that did have activation energy or greater do not have the energy now. So there are less Effective Collision (EC) decreasing the rate of product made called decreasing rate of reaction. |
5a) Increasing the temperature means that some energy is added equally to each reactant particles. So some reactant particles that did not have the activation energy or greater do have the energy now. So there are more Effective Collision (EC) increasing the rate of product made called increasing rate of reaction. |
6) Will discuss in class. |

7) Two or maximum of three reactant particle can make Effective Collision over a normal period of time. |
6b) Can change how many reactant particles are near each by anyone of the following: i) Increase concentration of reactants ii) Increasing surface area iii) Stirring iv) Increase pressure of gas reactant (at constant volume) v) Decrease volume of gas phase reactants 7) Will discuss in class. 8) Two or maximum of three reactant particle can make Effective Collision over a normal period of time. |
9) In a multiple step chemical reaction, the substance that is made in one substep and then consumed in a subsequent substep thereby the substance is not in the overall chemical reaction. |
