The delta G for the dissociation is 87,865 joule/kg.

The process is non-spontaneous because the value of Gibbs free energy is positive.

What is dissociation?

The breaking up of a compound into a simpler form that can be recombined under other conditions.

Given,

[tex]\bold{2NH_3 (g) = N_2(g) + 3H_2(g)}[/tex]

H = 145 kJ

Delta S = 195 J/k

Determining the G using the following process:

G = H -TS

[tex]\bold{G = (145\times10^3 J) -(293K \times 195 J/K})[/tex]

G = 87,865 Joules/K

Thus, the value of Delta G is  87,865 and the process is non-spontaneous.
