The Zero-order Rate Law (integral form) calculator computes the amount of reactant (concentration) at a certain point of time during a reaction.
INSTRUCTIONS: Choose units and enter the following:
- [A0] Initial Concentration of Substance A
- (k) reaction rate constant (units: mol/L*sec)
- (t) Duration of Reaction
Amount of Reactant [A]: The calculator returns the concentration of reactant in moles per liter (mol/L).

The Math / Science
The zero-order rate law (integral form)[1] equation calculates the amount of reactant at a certain point of time during the reaction. Remember that rate is a differential equation in mathematics and physics that can be integrated, a full integration of the differential form of zero-order can be found here. The zero-order rate law (integral form) equation is:
[A] = [A0] - k⋅t[2]
where
- [A] = Amount of Reactant
- [A0] = initial concentration of substance A in units of (mol/L)
- k = rate constant in units of (mol/L*sec)
- t = duration of the reaction in units of (sec)
