Which of the following statements are in accordance with the Arrhenius equation?
(i) Rate of a reaction increases with increase in temperature.
(ii) Rate of a reaction increases with decrease in activation energy.
(iii) Rate constant decreases exponentially with an increase in temperature.
(iv) Rate of reaction decreases with decrease in activation energy.
Answers (1)
The answer is the option (i, iv). According to Arrhenius equation, the rate of reaction increases with increase in temperature and decrease in the activation energy. It gets double with every 10° change. As the rate of reaction increases, there is an exponential increase in the rate constant of the reaction.
