In a zero order reaction, the rate=k since anything to the power of 0 is 1. Therefore the rate of reaction does not change over time and the [A] (for example) changes linearly. In a first order reaction, the rate and concentration are proportional. This means that if the concentration is doubled, the rate will double. Looking for the definition of RAT?
