Question

For the reaction N2(g) + 3 H2(g) → 2 NH3(g) ∆Grxn = –33 kJ mol-1 when all gases have a partial pressure of 1.0 bar. Changing the pressure of which gas to 2.0 bar will give the most negative value of ∆Grxn?

A.

N2

B.

H2

✓ Correct
C.

NH3

D.

The value of ∆Grxn will be the same regardless of the gas pressures.
