Question

Which of the following represents a second-order reaction?
Options
A Rate = k
B Rate = k[A]
C Rate = k[A]^2
Correct Answer
D Rate = k[A][B]^2
Correct Answer

Option C is the correct answer.

Detailed Explanation

The overall order of a reaction is the sum of the exponents. For Rate = k[A]^2, the exponent is 2, making it second order. Rate = k[A][B] would also be second order (1+1), but that option is not listed. Option D is third order.

Hint

A second-order reaction can have a rate proportional to the square of one reactant's concentration.
