Question
(#1)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.
f) Write the balanced equation for the overall reaction
g) What is the relationship between Guldberg and Waage's equilibrium constant and the ratio that you derived above in part (e)?
Explanation / Answer
NO2 ------> NO + O
O + O2 -----> O3
rate 1 = k1 [NO2]1
rate 2 = k2 [O]1[O2]1
NO2 + O2 <-----> NO + O3
