Question: What is the rate law for a reaction that is second order with respect to A and first order with respect to B?

Options:

Correct Answer: Rate = k[A]^2[B]

Solution:

The rate law is determined by the orders of the reactants. For second order in A and first order in B, the rate law is Rate = k[A]^2[B].

What is the rate law for a reaction that is second order with respect to A and first order with respect to B?

Step 1: Understand that the rate law describes how the rate of a reaction depends on the concentration of reactants.
Step 2: Identify the order of the reaction with respect to each reactant. In this case, it is second order with respect to A and first order with respect to B.
Step 3: Write the general form of the rate law: Rate = k[A]^m[B]^n, where k is the rate constant, m is the order with respect to A, and n is the order with respect to B.
Step 4: Substitute the values of m and n into the general form. Here, m = 2 (for A) and n = 1 (for B).
Step 5: The rate law becomes Rate = k[A]^2[B]^1.
Step 6: Simplify the expression. Since [B]^1 is just [B], the final rate law is Rate = k[A]^2[B].
