Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following factors does NOT typically affect the rate of a chemical reaction?
Temperature
Concentration of reactants
Presence of a catalyst
Volume of the reaction vessel
2. For a reaction A + B → C, if the rate law is Rate = k[A]²[B], what is the overall order of the reaction?
First order
Second order
Third order
Zero order
3. The is a proportionality constant in the rate law that relates the rate of reaction to the concentrations of reactants.
4. The of a reaction describes how the rate of reaction depends on the concentration of each reactant.
5. Consider the reaction: 2NO(g) + O₂(g) → 2NO₂(g). If the rate law for this reaction is determined experimentally to be Rate = k[NO]²[O₂], what would happen to the reaction rate if the concentration of NO was doubled?
6. Explain the concept of activation energy and its role in determining the rate of a chemical reaction.
7. For the hypothetical reaction A + B → C, the following initial rate data were collected:
a) Determine the order of the reaction with respect to A.
b) Determine the order of the reaction with respect to B.
c) Write the overall rate law for the reaction.
d) Calculate the value of the rate constant (k) with appropriate units.
