Chemical Reaction Rate Calculator

Initial Concentration (mol/L): Final Concentration (mol/L): Time Elapsed (seconds):

Result

Reaction Rate: - mol/L·s

A chemical reaction rate calculator helps determine how quickly a chemical reaction occurs by calculating the change in concentration of reactants or products over time. This tool is valuable for studying reaction kinetics in laboratories, industrial processes, and academic research.

The reaction rate is commonly expressed in units of concentration per time (e.g., mol/L·s).

How to Use the Chemical Reaction Rate Calculator

Step 1: Enter Known Parameters

Provide the following details:

• Change in concentration ($\Delta [Reactant]$ or $\Delta [Product]$)
• Time interval ($\Delta t$)

Step 2: Perform Calculation

The calculator applies the formula:

$$\text{Rate} = \frac{-\Delta [Reactant]}{\Delta t} \quad \text{or} \quad \frac{\Delta [Product]}{\Delta t}$$

Where:

• A negative sign for reactants indicates a decrease in concentration.

Example Calculation

If the concentration of a reactant decreases from 0.8 mol/L to 0.4 mol/L in 10 seconds, the reaction rate is:

$$\text{Rate} = \frac{-(0.4 - 0.8)}{10} = 0.04 \, \text{mol/L·s}$$
