Question 1

Consider the reaction 2H₂ + O₂→ 2H₂O
What is the ratio of the initial rate of the appearance of water to the initial rate of disappearance of oxygen?

◦ 1 : 1
◦ 2 : 1
◦ 1 : 2
◦ 2 : 2
◦ 3 : 2

Question 2

Consider the reaction 2O₃(g) → 3O₂(g). The following mechanism is proposed:

O₃ O₂ + O

O₃ + O → 2O₂

If we assume the second step of the mechanism is the rate determining step and the first step is a fast equilibrium step, which of the following rate laws is predicted by this mechanism?

◦ rate = k[O₃]
◦ rate = k[O₃]²[O₂]
◦ rate = k[O₃]²[O₂]^–1
◦ rate = k[O₃]²
◦ None of these are correct.
