Question
1.0 mol of N2(g), 1.0 mol of H2(g) and 1.0 mol of NH3(g) are placed in a 1.0 dm3 sealed flask and left to reach equilibrium. At equilibrium the concentration of N2(g) is 0.8 mol dm−3.
N2(g) + 3H2(g) \( \rightleftharpoons \) 2NH3(g)
What are the equilibrium concentration of H2(g) and NH3(g) in mol dm−3?
