Higher free energy of activation of a chemical reaction (at a given temperature) implies ____________________?
Correct answer: A. Slower rate of reaction
- A. Slower rate of reaction
- B. Higher rate of reaction
- C. Higher equilibrium conversion
- D. Both B. and C.
Explanation
A higher Gibbs free energy of activation means a smaller rate constant according to transition-state theory, so fewer molecules cross the activated-state barrier per unit time. Activation free energy affects reaction rate, not the equilibrium conversion.
