This calculator is designed for chemistry professionals and students to compute the rate constant of a chemical reaction using the Arrhenius equation. It helps to determine how reaction rates vary with temperature, which is crucial in many scientific and industrial processes.
All calculations are based on the Arrhenius equation: k = A * exp(-Ea / (R * T)), where R is the universal gas constant (8.314 J/mol·K). This formula provides a precise method for calculating the rate constant of reactions.
\( k = A \cdot e^{\frac{-E_a}{R \cdot T}} \)
Assume a reaction with A=1.5x1012 s-1, Ea=75,000 J/mol, and T=298 K. Using the Arrhenius equation, you can find k by substituting these values into the formula.
