We’re being asked to determine what would happen to the half-life of the reaction if the concentration of A is cut in half.
A → products k = 0.15 mol/(L•S)
We're going to determine the change in half-life using the following steps:
Step 1: Determine the order of the reaction using the rate constant.
Step 2: Determine the change in half-life.
The reaction A → products has a rate constant of 0.15 mol/(L s). If the concentration of A is cut in half, the half-life of the reaction will
A) decrease by a factor of 1/2.
C) decrease by a factor of 1/4.
D) remain constant.
