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?

**First, determine the concentrations of A and B.**Calculate the molar concentration per unit volume of both reactants.

**Next, determine the partial orders of reaction.**Calculate the partial orders of reaction with respect to reactants A and B.

**Finally, calculate the rate constant.**Calculate the rate constant using the formula above.

## FAQ
