What two questions about a chemical reaction does Kinetics answer?<br> a) <br> b) <br> <br> 2. What one question about chemical reactions does kinetics NOT answer and what chemical concept does answer this question?<br> <br> <br> 3. What is the name of the theory (and give a one sentence explanation) that all of kinetics are based on? _______________________<br> <br> 4a. For Mr. <nowiki>Mr. McLeod's class</nowiki>, what two words must be in all answers (except reaction mechanism problems) of kinetics?__________________<br> <br> 4b. What are the two factors that determine the answer from Question #4a above?<br> a) <br> b) <br> <br> 5. On the back of this page, explain how increasing temperature increases the rate of reaction. In your explanation, use (including explaining graph) the Kinetic energy diagram as part of your explanation. <br> <br> <br> <br> 6a. On the back of this page, answer the same questions as in Q5. above except for having more reactant particles near each other per volume.<Br> <br> <br> <br> 6b. Give at least two ways that you can get more reactant particles near each other per volume.<br> <br> i) <br> <br> ii)<br> <br> <br> 7. On the back of this page, draw the potential energy diagram for an exothermic reaction and define each section of the diagram. Show where the heat of reaction deltaH<sub>rxn</sub> is located on the graph and explain how you calculate it. What is the "sign" of deltaH<sub>rxn</sub> for an exothermic reaction. Then show on the graph and through effective collisions how adding a catalyst increases rate of the reaction.<br> <br> <br> <br> 8.Most overall chemical reactions are multi-step (ie all the reactants do not react all at once). What is the reason why this is so? <br> <br> 8. State the two requirement for a substance to be a catalysis.<br> a) <br> b)<br> <br> 9. Define what an intermediate is. <br> <br> <P style="page-break-before: always"> <br> 10. One mechanism for the destruction of ozone (O<sub>3</sub>) in the upper atmosphere is<br> O<sub>3(g)</sub> + NO<sub>(g)</sub> --> NO<sub>2(g)</sub> + O<sub>2(g)</sub> <b>Slow</b><br> NO<sub>2(g)</sub> + O<sub>(g)</sub> --> NO<sub>(g)</sub> + O<sub>2(g)</sub> <b>Fast</b><br> __________________________________________________________________________________________<br> O<sub>3(g)</sub> + O<sub>(g)</sub> ---> 2 O<sub>2(g)</sub> <b>Overall Reaction</b><br> (It may be easier to answer a & b if you first thing about the definitions)<br> a. Which species are catalysts.<br> b. Which species are intermediate.<br> c. I did some experiments and found that if I increased the concentration of O<sub>3</sub>, the rate of reaction increased and if I increased the concentration of O<sub>(g)</sub>, the rate of reaction also would increase. Does the above reaction mechansim support this data or not? Explain. <br>
