Consider the reaction
A + B $\rightarrow$ C + D rate = k[A]²
The time it takes for [A] to decrease from 1.0 to 0.50 M is the same as the time it takes for [A] to decrease from0.50 to 0.25 M.

Question

Consider the reaction A + B $\rightarrow$ C + D rate = k[A]² The time it takes for [A] to decrease from 1.0 to 0.50 M is the same as the time it takes for [A] to decrease from0.50 to 0.25 M.

The reaction is second-order with respect to A, so the time intervals for equal concentration decreases are not the same. The time taken for the concentration to halve increases as the concentration decreases.
