Question

For a second-order reaction, a plot of which function versus time will yield a straight line?
Options
A [A] vs. t
B ln[A] vs. t
C 1/[A] vs. t
Correct Answer
D [A]² vs. t
Correct Answer

Option C is the correct answer.

Detailed Explanation

The integrated rate law for a second-order reaction is 1/[A] = kt + 1/[A]₀, which is in the form y = mx + b. A plot of 1/[A] versus time gives a straight line with slope k.

Hint

Recall the integrated rate laws for different orders.
