Question

When the rate for the reaction
2NO+ 0
2 NO,
was studied, the rate was found to double when the O₂ concentration was doubled while
the NO concentration was unchanged. It was also found that the rate quadruples when
the NO concentration is doubled while the O, concentration is unchanged.
o What is the rate law expression for this reaction? P
Two mechanisms were proposed for this reaction as shown below.
PROPOSAL I
Step 1:
Step 2:
NO + O₂
NO NO
PROPOSAL II
Step 1
Step 2
Step 3
NO NO
0₂ + N₂O₂
N₂0₂
NO:
NO,
N₂O₂
N₂O₁
NO₂
(fast)
NO, (alem, RDS)
(slow, RDS)
(test)
NO₂ (fast)
b. Write a predicted rate low for each proposed mechanism. In your predicted rate law,
make sure no intermediates are present in the overall expression
c. Which proposed mechanism I or II agrees with the rate kw expression that you
determined above? You must also explain your reasoning or no credit will be given Place
