The complete mechanism for a reaction is considered to occur in two steps,one of which is slow and the other fast:
A + B → C + D slow
A + C → E + F fast
What is the net chemical equation predicted by this mechanism?

Question

Quizplus · Accepted Answer

The net chemical equation is obtained by adding the two steps and canceling out the intermediates (species that appear on both sides of the equation). In this case, C is produced in the first step and consumed in the second, so it cancels out. The net equation is 2A + B → D + E + F, as A is consumed twice.
