Question

A certain first-order reaction has a rate constant of 2.45×10−2s−1 at 21 ∘C. What is the value of the rate constant at 61 ∘C if the activation energy is 75.5 kJ/mol?

Answer 1

To calculate the rate constant at 61 °C, we need to use the Arrhenius equation with the given activation energy and the rate constant at 21 °C. Unfortunately, the provided information is insufficient to complete the calculation.

Step-by-step explanation:

The value of the rate constant at 61 °C for a first-order reaction with a given rate constant at 21 °C and an activation energy can be calculated using the Arrhenius equation. This equation relates the rate constants at different temperatures with the activation energy and the universal gas constant, R. However, to provide the correct answer, we must have the initial rate constant at 21 °C and the activation energy for the reaction.
