Given the equilibrium system below determine the equilibrium concentration of N2Cl2 (g) given that 0.5 moles of N2 (g) and 1.5 moles of Cl2 (g) are initially placed in a 2-liter container. K for the system is 1.5 x 10-5 (a trick to avoid the quadratic equation). Show all work and round to the correct number of sig figs. N2 (g) + Cl2 (g) ↔N2Cl2 (g) K = 1.5 x 10-5
