1. The statements in the following multiple choices deal with various aspects of
reaction rates. Choose the statement which is false.
a. High surface area makes heterogeneous catalysts more effective than high
mass.
b. Slow reactions have high reaction rates.
c. Increasing reactant concentrations increases (forward) reaction rates.
d. Reaction rates can be increased with the use of catalysts.
e. Reaction rates increase as temperature increases.
2. The statements in the following multiple choices deal with various aspects of
reaction rates. Choose the statement which is true.
a. Speeding up a fast step significantly increases the overall reaction rate.
b. Decreasing reactant concentrations increases (forward) reaction rates.
c. The more stable the reactants are the higher the reaction rate.
d. High surface area makes heterogeneous catalysts more effective than high
mass.
e. High mass makes heterogeneous catalysts more effective than high surface
area.
3. For the gas-phase reaction shown below, describe how the rate of change of H2O
is related to the rate of change of CO2.
C4H10(g) + 6O2(g) 4CO2(g) + 5H2O(g)
4. For the gas-phase reaction shown below, describe how the rate of change of H2O
is related to the rate of change of NH3.
4NH3(g) + 5O2(g) 4NO(g) + 6H2O(g)

5. Consider the combustion of ether:
C4H10O(g) + 6O2(g) 4CO2(g) + 5H2O(g)
If H2O is produced at the rate of 0.13 mol/s, what is the rate of production of
CO2?
6. Consider the combustion of octane:
2C8H18(g) + 25O2(g) 16CO2(g) + 18H2O(g)
If CO2 is produced at the rate of 0.31 mol/s, what is the rate of consumption of
O2?
7. Consider the following reaction:
O2(g) + 2NO(g) 2NO2(g)
The rate law for this reaction is first order in O2(g) and second order in NO(g).
Write the correct rate law for this reaction.
8. Consider the following reaction:
2NO(g) +2H2(g) N2(g) + 2H2O(g)
The rate law for this reaction is second order in NO(g) and first order in H2(g).
Write the correct rate law for this reaction.
