Nitrogen and hydrogen are mixed in a reaction vessel. The reaction reaches equilibrium giving a mixture of nitrogen, hydrogen and ammonia gases. N₂ + 3H₂ ⇌ 2NH₃ The mixture of gases present at equilibrium at a total pressure of 300 atm is shown. gas: nitrogen, number of mol in mixture: 180 gas: hydrogen, number of mol in mixture: 590 gas: ammonia, number of mol in mixture: 160 What is the equilibrium constant, Kp, for the forward reaction?
A6.65 x 10⁻⁶ atm⁻²
B7.13 x 10⁻⁵ atm⁻²
C0.599 atm⁻²
D1.50 x 10⁵ atm⁻²
✓ Correct answer
A: 6.65 x 10⁻⁶ atm⁻²
