A chemist is studying the following reaction: 2A + B-D During the reaction the chemist observes an intermediate C that takes a long time to appear but disappears very quickly. The rate observed experimentally was: Rate exp = A+A C slow C+B D fast Is this mechanism consistent with the observed experimental rate law? Justify your answer in 2 sentences.

Question

Hi, what is the correct answer to this question?

A chemist is studying the following reaction: 2A + B-D
During the reaction the chemist observes an intermediate C that takes a long time to appear but
disappears very quickly. The rate observed experimentally was: Rate exp =
A+A C
slow
C+B D
fast
Is this mechanism consistent with the observed experimental rate law? Justify your answer in 2
sentences.
