Zero-order rate law

The Zero-order Rate Law calculator computes the rate of a reaction not dependent on the concentration of its reactants.

INSTRUCTIONS: Enter the following:

• ([A]) Concentration of A 
• (k) Constant in (mol/L*sec)

Rate:  The calculator returns the rate in moles per liter per second.

The Math / Science

The Zero-order rate law^[1] equation calculates the rate of a reaction that does not depend on the concentration of its reactants. Since the rate is independent of the reactant's concentration the rate will be constant but only of a certain amount of time. This rate reaction observation is confirmed by the theory of Michaelis-Menten kinetics^[3], where a catalyzed reaction will have a constant rate up until a certain point in time where the rate starts to decrease / This is due to less substrate (reactants) binding to the catalyst.

The Math

The equation is:
      Rate = k[A]⁰ = k
Where 

• [A] is the concentration of substance A in units (mol/L)
• k is the rate constant in units of (mol/L*s)
