Arrhenius Equation Calculator
The Arrhenius Equation is a mathematical formula that explains the relationship between the rate constant of a chemical reaction and the temperature. This equation is fundamental in the field of chemical kinetics and plays a crucial role in understanding how temperature affects reaction rates.
What is the Arrhenius Equation?
The Arrhenius Equation is represented as:
k = A * e^(-Ea / RT)
Where:
- k = Rate constant
- A = Frequency factor (pre-exponential factor)
- e = Euler's number (approximately 2.718)
- Ea = Activation energy
- R = Universal gas constant (8.314 J/mol·K)
- T = Temperature in Kelvin

Why is the Arrhenius Equation Important?
The Arrhenius Equation is vital for determining how fast a reaction will occur at a given temperature. It provides insight into the energy barrier (activation energy) that reactants must overcome to form products. By adjusting the temperature, scientists can control the speed of chemical reactions, which is key in fields such as chemical engineering, biology, and environmental science.
How to Use the Arrhenius Equation Calculator
