The rate is proportional to the concentration of the reactant to the power of 0. It has no effect.
1 of 14
First order
The rate is proportional to the concenrtration of the reactant to the power of one.
2 of 14
Second order
The rate is proportional to the concentration of the reactant to the power of two.

Concentration/Time graph
Zero order: straight line with negative gradient, first order: downward curve with decreasing gradient and Second order: downward curve steeper at start but levels off more slowly
