At 29°C, Kp = 5.3 ✕ 102 atm−2 for the following reaction. N2(g) + 3 H2(g) equilibrium reaction arrow 2 NH3(g) When a certain partial pressure of NH3(g) is put into an otherwise empty rigid vessel at 29°C, equilibrium is reached when 55.1% of the original ammonia has decomposed. What was the original partial pressure of ammonia before any decomposition occurred?
