In the Haber process, ammonia is synthesized from nitrogen and hydrogen: N2(g) + 3H2(g) → 2NH3(g) ΔG° at 298 K for this reaction is -33.3 kJ/mol. The value of ΔG at 298 K for a reaction mixture that consists of 1.9 atm N2, 1.6 atm H2, and 0.65 atm NH3 is .

Therefore the value of  ΔG is - 39.35 KJ

Explanation:

Haber process: In the Haber process combines with nitrogen and hydrogen to make ammonia.

N₂(g) +3H₂(g) →2NH₃(g)

ΔG° at 298k for the above reaction is -33.3 kJ/ mol.

Partial presser of nitrogen = = 1.9 atm

Partial presser of hydrogen = = 1.6 atm

Partial presser of ammonia = = 0.65 atm

T= 298K

To find ΔG we use the following formula

= Partial presser of A

=Partial presser of B

=Partial presser of C

= Partial presser of D

R= ideal gas constant = 8.314 J/K

For the given equation

    -

   = - 39.35 KJ

Therefore the value of  ΔG is - 39.35 KJ
