Question

The true statement for the formula \( K = Ae^{-E_a / RT} \) is:

• A. \( K \) is equilibrium constant
• B. \( K \) R is Rydberg constant
• C. \( K \)A is adsorption coefficient
• D. \( K \)Ea is activation energy

Hint:

The Arrhenius equation explains how temperature and activation energy affect reaction rates.

Answer 1

The Correct Option is D

The formula \( K = Ae^{-E_a / RT} \) is the Arrhenius equation, where:
- \( K \): Rate constant,
- \( A \): Pre-exponential factor,
- \( E_a \): Activation energy,
- \( R \): Gas constant,
- \( T \): Temperature.
