Question

A mixture of 0.100 mol of NO, 0.050 mol of H₂ and 0.10 mol of H₂O is placed in a 1.0-L vessel at 300 K. The following equilibrium is established:

2NO(g) + 2H₂(g) ⇆ N₂(g) + 2H₂O(g).

At equilibrium [NO] = 0.062M. Calculate the equilibrium concentrations of H_2, N₂ and H₂O and Keq.

Strategy:

Using the balanced chemical equation, write the equilibrum constant expression, Kc, then substitute the given equilibrium concentrations to it.
