The equilibrium reaction of nitrogen dioxide and oxygen to make nitrogen monoxide and ozone, O3, involves an elementary reaction for both the forward and reverse reactions:

a) Write the two elementary reactions involved in this equilibrium reaction

b) Write the rate laws for the two elementary reactions you listed in part (a)

c) What is true of these two reaction rates (forward and reverse) at equilibrium?
d) Substitute expressions from part (b) into your answer for part (c) above:

e) Rearrange your result from part (d) into an equality that has the ratio of the forward rate constant divided by the reverse rate constant on one side and all other terms on the other side of the equal sign.

Answer #1

(1) step 1: NO + O? ? NO? + O?
step 2: NO? + O? ? NO + O?
Where the second step is just the reverse of the first step. Now see if you can do the rest.
Mark, the question wants you to consider an equilibrium reaction with just one forward step and one reverse step [this is made even clearer in the wording of part (c): "What is true of these 2 reaction rates (forward and reverse) at equilibrium?".] The reaction does make nitrogen dioxide and oxygen, it is just that "oxygen" means dIoxygen, the normal diatomic stable form of oxygen, the element
