Question

In the reaction \( 2A + B \rightarrow C \), if the rate law is \( \text{Rate} = k[A]^2[B] \), what is the overall order of the reaction?

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

To determine the overall order of a reaction, simply add the exponents of all concentration terms in the rate law.

Answer 1

The Correct Option is C

The overall order of a reaction is determined by summing the exponents of the concentration terms in the rate law. 

In this case, the rate law is given as \( \text{Rate} = k[A]^2[B] \). 

The exponent of \( [A] \) is 2 and the exponent of \( [B] \) is 1. 

Therefore, the overall order is \( 2 + 1 = 3 \).
