For the problem:
Consider the reaction A+B-->C+D rate=k[A]squared
The time it takes for [A] to decrease from 1.0 to 0.50M is the same as the time it takes [A] to decrease from 0.50 to 0.25M. True or false?

Why is this false?

Because it is second order so if you use the equation 1/[a]=kt+1/[a0] you will see that 1-1/.5 is not the same as 1/.5-1/.25.
