Which of the following is the correct Arrhenius equation?
Correct answer: B. K=Ae^-Ea/RT
- A. K-Ae^-Ea/QT
- B. K=Ae^-Ea/RT
- C. K=Ae^-Ea/ST
- D. K=Ae^-Ea/UT
Explanation
Option B is the correct Arrhenius equation, where A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
