Here are following answer to the Question in [[Review HW for Kinetics - Revised 2016]].

1a) Reaction Rate - How fast does the reaction go (how fast make products or reduce reactants). 
 
1b) Reaction Mechanism - How do reactant particle collide or combine to get products (is it a one or multiple step reaction) 
 
 
2) Does the reaction occur or not. As you remember, Thermodynamics determines that question (Gibbs Free Energy differences). 
 
3) Collision Theory 
 
4a) Effective Collision (EC) 
 
4b) Reactant particles must have the Activation Energy or greater AND near each other & right spatial (3-D) orientation. 
 
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. 
 
6) Will discuss in class. 
 
7) Two or maximum of three reactant particle can make Effective Collision over a normal period of time. 
 
8) Changes the activation Energy thereby rate of reaction without being consumed in the reaction. 
 
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. 
 
10a) NO 
10b) NO2 
10c) 2020-2021 Students do not have to do this part
