ΔG=ΔG+RTln((PNH3)2PN2(PH2)3)

Explanation:

The relationship between ΔG and pressure is: ΔG=ΔG+RTlnQ

Where Q is the reaction quotient, that in case of a reaction involving gaseous reactants and products, pressure could be used.

For example: N2(g)+3H2(g)2NH3(g)

The reaction quotient is: Q=(PNH3)2PN2(PH2)3

Therefore, ΔG=ΔG+RTln((PNH3)2PN2(PH2)3)
