If activation energy, E a of the reaction is equal to R T then
Options
- AThe rate of reaction will be independent on initial concentration of reactant.
- BThe rate constant becomes approximately equal to 37 % of the Arrhenius constant
- CThe rate of reaction becomes infinite
- DThe rate of reaction always be first order.
Correct answer
B. The rate constant becomes approximately equal to 37 % of the Arrhenius constant
Step-by-step solution
k = A e - E a / R T When E a = R T , then k = A e = A 2.718 - ~ 0.37 A The rate constant becomes approximately equal to 37% of the Arrhenius constant
