NEET Chemistry Rate of Reaction MCQ Question
What is the rate constant k at 700K if the activation energy Ea is 209 kJ/mol and the frequency factor A is 1.60 × 10^11 s^-1?
6.36 × 10^-3 s^-1
50 × 10^-3 s^-1
20 × 10^-3 s^-1
8.00 × 10^-3 s^-1
Correct Answer
Detailed Explanation
Using the Arrhenius equation log k = -Ea/(2.303RT) + log A, with Ea = 209 kJ/mol, A = 1.60 × 10^11 s^-1, R = 8.314 J/mol K, and T = 700K, we find k = 6.36 × 10^-3 s^-1.
