In the Haber Process,ammonia Is Synthesized from Nitrogen and Hydrogen $\mathrm { N } _ { 2 }$

In the Haber process,ammonia is synthesized from nitrogen and hydrogen:
$\mathrm { N } _ { 2 }$ (g) + $3 \mathrm { H } _ { 2 }$ (g) ? $2 \mathrm { NH } _ { 3 }$
(g) ?_rG° at 298 K for this reaction is -33.3 kJ mol^-1.The value of ?_rG at 298 K for a reaction mixture that consists of 1.7 atm $\mathrm { N } _ { 2 }$ ,1.1 atm $\mathrm { H } _ { 2 }$ ,and 0.55 atm $\mathrm { NH } _ { 3 }$ is ________ kJ mol^-1.

A) -5.02 × 10³
B) -4.5
C) -72.2
D) -35.3
E) -38.3
