Question

Consider two reactions having same Arrhenius factor A, but different energy of activation.
(i) $A \to B; E a_{1} = 20 kJ$
(ii) $C \to D; E a_{2} = 30 kJ$
Both are at temperature $25 ° C$
If temperature in both reaction is increased slightly in such a way that change in temperature in both case is same than choose the correct options.

Arrhenius equation; d l n k = E a R T 2 d T Here, T and dT same and positive d l n k α E a l n k 2 - l n k 1 α E a l n K 2 K 1 α E a So, if temperature increases, then rate of reaction having more E a increases more sharply.
