Question:

The rate law of the single-step reaction 2A + B → C, is given by which of the following?

Options:

Rate = k[A][B]

Rate = k[A]2[B]

Rate = k[A][B]2

Rate = k[A][B]1/2

Correct Answer:

Rate = k[A]2[B]

Explanation:

A rate law shows how the rate of a chemical reaction depends on reactant concentration.

Rate of a reaction = k [A]x[B]y

For the above reaction coefficient of A is 2 and B is 1. So the rate of the reaction = k[A]2[B]
