NEET Chemistry Activation Energy MCQ Question
A reaction has rate constants k1 and k2 at temperatures T1 = 300 K and T2 = 350 K, respectively. If the activation energy Ea is 50000 J/mol and the gas constant R is 8.314 J/mol·K, find the ratio k2/k1.

Correct Answer
Detailed Explanation
Using the Arrhenius equation ln(k2/k1) = Ea/R * (1/T1 - 1/T2), substituting given values results in a ratio k2/k1 ≈ 2.28.
