Explain with the help of the Arrhenius equation, how do the rate of reaction changes with temperature.

उत्तर
Arrhenius equation k = `"Ae"^("-E"_"a"/"RT")` shows that as the temperature rises, `"E"_"a"/"RT"` decreases, this causes an increase in `-"E"_"a"/"RT"`. This increases k and the rate of reaction.
