Chapter 14.4, Problem 8PE

The equilibrium constant (K_c) for the formation of nitrosyl chloride, an orange-yellow compound, from nitric oxide and molecular chlorine

$2\text{NO}(g)+{\text{Cl}}_2(g)\rightleftharpoons 2\text{NOCl}(g)$

is 6.5 × 10⁴ at 35°C. In a certain experiment, 2.0 × 10⁻² mole of NO, 8.3 × 10⁻³ mole of Cl₂, and 6.8 moles of NOCl are mixed in a 2.0-L flask. In which direction will the system proceed to reach equilibrium?
