Enter the reaction rate, molar concentrations of A and B, and the partial orders of reaction of A and B to calculate the rate constant.

Rate Constant Formula

The following formula is used to calculate a rate constant.

k = R / (A^m * B^n)

  • Where R is the reaction rate
  • A is the molar concentration of substance A
  • m is the partial order of reaction of substance A
  • B is the molar concentration of substance B
  • n in the partial order of reaction of substance B

Rate Constant Definition

A rate constant is a term used in chemistry to define the ratio or proportionality of the rate of reaction to the concentrations of the reactants.

Rate Constant Example

How to calculate a rate constant?

  1. First, determine the concentrations of A and B.

    Calculate the molar concentration per unit volume of both reactants.

  2. Next, determine the partial orders of reaction.

    Calculate the partial orders of reaction with respect to reactants A and B.

  3. Finally, calculate the rate constant.

    Calculate the rate constant using the formula above.
