Arrhenius Equation Calculator

What is Arrhenius Equation Calculator?

The Arrhenius Equation Calculator allows users to compute the rate constant (k) of a chemical reaction at a given temperature using the formula k = A * exp(-Ea / RT), where A is the pre-exponential factor, Ea is the activation energy, R is the universal gas constant, and T is the temperature in Kelvin.

How to Use Arrhenius Equation Calculator?

To use the Arrhenius Equation Calculator, enter the following values:

  • Activation Energy (Ea): The energy required for the reaction to occur, typically in J/mol.
  • Temperature (T): The temperature at which the reaction occurs, in Kelvin (K).
  • Pre-exponential Factor (A): A constant factor that accounts for the frequency of collisions between reacting molecules.

After inputting these values, press "Calculate Rate Constant" to get the result.

What is the Formula of Arrhenius Equation Calculator?

The Arrhenius equation formula used by this calculator is:

k = A * exp(-Ea / (R * T))

Where:

  • k = Rate constant
  • A = Pre-exponential factor
  • Ea = Activation energy in J/mol
  • R = Universal gas constant (8.314 J/mol·K)
  • T = Temperature in Kelvin
Advantages and Disadvantages of Arrhenius Equation Calculator
Advantages:
  • Quick and easy way to calculate the rate constant for reactions.
  • Helps in studying the effect of temperature on reaction rates.
