Question

First order reactions are important in chemical reactions as well as in pharmacology. First order refers to the rate of a reaction. If the reaction is Aïƒ B, then stating that it is first order implies that rate=k*[A], where k is some constant and [A] is the concentration of A. Which of the following does not hold true for such an order reaction?

A) The slope of log[A] over time is linear

B) Half-life depends on the concentration of A

C) If [A] doubles, so will the rate of the reaction

D) Changing [B] will have no impact on the rate
