Question

According to the Arrhenius equation, $k=A{e}^{E_A/\left(RT\right)}$, what happens to the rate constant $k$ of the reaction as the temperature of the reaction is increased?

• A. The rate constant would decrease
• B. The rate constant would increase
• C. There is no effect in either direction
• D. It cannot be determined from the given information

Answer 1

Answer: (B)

The rate constant would increase

We know that the rate constant increases for an increase in temperature (and as activation energy increases, the rate constant decreases. Now, since the rate constant increases, this implies that the rate of reaction increases with temperature.
