What fraction of collisions will have sufficient energy to react for a gas whose activation energy is 68 kJ/mol at 25°C?

Question

Quizplus · Accepted Answer

The fraction of collisions with sufficient energy to react is given by the Boltzmann distribution:$$f = e^{-Ea/RT}$$where:* f is the fraction of collisions with sufficient energy* Ea is the activation energy* R is the gas constant* T is the temperaturePlugging in the given values, we get:$$f = e^{-68 kJ/mol / (8.314 J/mol K * 298 K)} = 2 × 10^{-12}$$Therefore, the correct answer is A) 2 × 10^{-12}.
