Question

what is the overall order of the following reaction that has a rate law of rate = ka b ? the reaction a + 2b → c a) zero b) first c) second d) third

Explanation:

Step1: Recall the formula for reaction order

The overall order of a reaction is the sum of the exponents in the rate law. For the rate law \( \text{Rate} = k[\text{A}][\text{B}] \), the exponent of \([\text{A}]\) is \(1\) and the exponent of \([\text{B}]\) is \(1\).

Step2: Calculate the overall order

Add the exponents: \(1 + 1=2\).

Answer:

C. second
