उत्तर

(a) only

Explanation:

Exothermic reaction is a chemical reaction in which the enthalpy change is negative and energy is released in the form of light and heat.

As we all know, ΔH is negative.

Activation energy (forward reaction) – (backward reaction)

(Forward reaction) – Ea (backward reaction)

The product's exothermic energy exceeds the activation energy of the reactant.

(b) Rate constant ‘k’ of a reaction varies with temperature ‘T’ according to the equation:

`logk=logA-E_a/2.303R(1/T)`

Where Ea is the activation energy. When a graph is plotted for `logk Vs. 1/T` a straight line with a slope of −4250 K is obtained. Calculate ‘Ea’ for the reaction.(R = 8.314 JK−1 mol−1)
