Formula:Concentration = Initial Concentration - Rate Constant × Time

Introduction to Zero Order Kinetics Rate Equation

The zero order kinetics rate equation describes the rate at which a substance is consumed or produced over time. In this formula, Concentration represents the concentration of the substance at a given time, Initial Concentration is the initial concentration of the substance, Rate Constant is the rate constant of the reaction, and Time is the time elapsed. The result is expressed in the same units as the initial concentration.

Parameter usage:

Data validation

The initial concentration, rate constant, and time should be greater than or equal to zero.


This formula is used to calculate the concentration of a substance over time in a zero order kinetics reaction.
