The standard Gibbs energy of formation of NH 3 (g) is 16.5 kJ mol 1 at 298

Question:

The standard Gibbs energy of formation of NH₃(g) is −16.5 kJ mol⁻¹ at 298 K. What is the reaction Gibbs energy when the partial pressures of the N₂, H₂, and NH₃ (treated as perfect gases) are 3.0 bar, 1.0 bar, and 4.0 bar, respectively? What is the spontaneous direction of the reaction in this case?
