5. A mixture of 0.100 M of NO, 0.05 M of H₂ and 0.10 of H₂O is placed in a 0-L vessel. The following equilibrium is established:

2NO(g) + 2H₂(g) N₂(g) + 2H₂O(g)

At equilibrium [NO] = 0.062 M. a) Calculate the equilibrium concentrations of H₂, N₂ and H₂O; b) Calculate K_c if the equilibrium constant (K_p) is 2.77 x 10^-4atm.
