In a first order chemical reaction, the velocity of the reaction is proportional to the , while in a zero order reaction, the velocity of the reaction is proportional to the .
A) amount of enzyme; concentration of substrate
B) concentration of substrate; amount of enzyme
C) concentration of substrate; speed of the reaction
D) speed of the reaction; concentration of substrate

Question

Quizplus · Accepted Answer

In a first order reaction, the rate is proportional to the concentration of the substrate. In a zero order reaction, the rate is independent of the concentration of the substrate and is often determined by the amount of enzyme present.

In a First Order Chemical Reaction, the Velocity of the Reaction
