Consider the Following Equilibrium: 2NOCl(g) 2NO(g)+ Cl₂(g)with K = $\times$

Consider the following equilibrium: 2NOCl(g) 2NO(g) + Cl₂(g) with K = 1.6 $\times$ 10^-5.In an experiment,1.00 mole of pure NOCl and 1.00 mole of pure Cl₂ are placed in a 1.00-L container.
-If x moles of NOCl react,what is the equilibrium concentration of Cl₂?

A) x
B) x
C) 1 + x
D) 1 + x
E) 1 + 2x
