Refer picture given below.
(a) Calculate `DeltaH` for the reaction and the energy of activation for the forward reaction as well as backward reaction.
(b) The dotted curve is in the presence of a catalyst. What is the energy of activation for the two reactions in the presence of catalyst?
( c) Will the catalyst change the extent of reaction?

Explanation

(a) `DeltaH = E_(a(p)) - E_(a(r )) = 100-110 = -10kJ`
form the given picture, in the absence of catalyst, Energy of activation for the forward reaction
`= 140-110 = 30kJ`
Energy of activation for the backward reaction
`= 140 - 100 = 40 kJ`
(b) In the presence of catalyst,
Energy of activation for the forward reaction
`= 120-110=10kJ`
Energy of activation for the backward reaction
`= 120-100=20kJ`
(c ) No
