Question

1. The simplest ammonia formation is from nitrogen and hydrogen. Consider the reversible reaction N2(g) + 3H2(g) → 2NH3(g) The standard enthaply and Gibbs free energy of formation one mole NH3 is ∆H◦ m = −46.11 kJ mol−1 and ∆G◦ m = −16.78 kJ mol−1 .

(a) What is equilibrium constant at standard condition (25°C and 1 atm)?

(b) What is equilibrium constant at 60°C and 1 atm?

(c) What is the Gibbs free-energy change relative to that under standard conditions of forming 1 mol of NH3 at 25°C if 10.0 bar of N2 and 10.0 bar of H2 are reacted to give 0.01 bar of NH3?
