Reaction Kinetics Review Worksheet 1.

What 5 factors affect reaction rate?

2.

For each of the reactions below, draw a potential energy diagram and label the following parts: both axes, activation energy of both forward and reverse reactions, heat of reaction and site of activated complex formation. a)

AB + C  AC + B

H = 65 kJ and EA(fwd) = 99 kJ.

3.

b)

A2 + B2  2 AB

EA(fwd) = 75 kJ, EA(rev) = 143 kJ

Hydrogen reacts more quickly with Cl2 than with Br2. Use this experimental evidence to explain each of the following: a) The relative strengths of the bonds between atoms in Cl2 and Br2 molecules.

b) The relative magnitudes of the activation energies for the two reactions.

Given the reaction: 4HBr + O2  2H2O + 2Br2 This reaction is thought to take place by means of the following mechanism: Step 1: HBr + O2  HOOBr

(slow)

Step 2: HBr + HOOBr  2HOBr

(fast)

Step 3: 2HBr + 2HOBr  2H2O + 2Br2

(fast)

a) Identify the intermediates

b) A catalyst is discovered which increases the rate of Step 3. How will this affect the rate of the overall reaction? Explain your answer.

c) A catalyst is discovered which increases the rate of Step 1. How will this affect the rate of the overall reaction? Explain your answer.

d) Which step(s) has the greatest activation energy? Explain.

e) How many "bumps" will the potential energy diagram for the reaction mechanism have?

f) Sketch a potential energy diagram to show the shape of the curve you might expect for the reaction in this question. The overall reaction is exothermic! Make sure you get the "bumps" the correct relative sizes.
