Enter the change in quantity of the substance during the reaction and the time into the calculator to determine the reaction velocity.

Reaction Velocity Formula

The following equation is used to calculate the Reaction Velocity.

RV = CP / T

  • Where RV is the reaction velocity (quantity/time)
  • CP is the change in the parameter/quantity being analyzed
  • T is the time (seconds)

What is a Reaction Velocity?

Definition:

A reaction velocity describes the rate of change of a parameter, such as mass, during a chemical reaction.

How to Calculate Reaction Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Reaction Velocity.

First, determine the change in the parameter/quantity being analyzed . In this example, the change in the parameter/quantity being analyzed is found to be 50 kg.

Next, determine the time. For this problem, the time is found to be 5 seconds.

Finally, calculate the Reaction Velocity using the formula above:

RV = CP / T

RV = 50 / 5

RV = 10 kg /s
