Name __________________________
1. (3 points) Describe three of the factors that affect the rate of a reaction and describe how
each factor affects the rate of reaction?
a.
b.
c.
2. (3 points) The formation of ammonia is one of the most important processes in the
chemical industry: N2(g) + 3H2(g) → 2NH3(g)
a. Express the rate in terms of changes in [N2], [H2], and [NH3]
b. When [N2] is decreasing at 0.10mol/Ls, how fast is [NH3] increasing?
c. Can you write the rate law with reaction orders for this reaction?
If yes, write the rate law. If not, explain why not.
3. (4 points) Phosgene is a toxic gas prepared by the reaction of carbon monoxide and
chlorine gas:
CO(g) + Cl2(g) → COCl2(g)
