Consider the following hypothetical reaction: 2P + Q→ 2 R + S. The following mechanism is proposed for this reaction: P + P = T (fast) Q + T → R+ U (slow) U-R + S (fast) Substances T and U are unstable intermediates. What rate law is predicted by this mechanism? (a) Rate = k[P]? (b) Rate = k[P][Q] (c) Rate = k[P]°[QI (d) Rate = k[P][Q? (e) Rate = k[U]

Question
Consider the following hypothetical reaction:
2P + Q→ 2 R + S. The following mechanism is proposed
for this reaction:
P + P = T (fast)
Q + T → R+ U (slow)
U-R + S (fast)
Substances T and U are unstable intermediates. What rate law
is predicted by this mechanism?
(a) Rate = k[P]? (b) Rate = k[P][Q] (c) Rate = k[P]°[QI
(d) Rate = k[P][Q? (e) Rate
= k[U]
