Consider the equilibrium 2NO (g) <---> 2NO (g) + Cl2 (g). In a 1 L container @ equilibrium there are 1.0 mol NOCL, 0.70 mol NO, and 0.40 mol Cl2. @ constant temperature and volume, 0.10 mol NaCl is added. What are the concentrations in the "new" equilibrium in comparison to the concentrations in the "old" equilibrium?
You may want to clarify the problem. Is that 2NOCl ==> 2NO + Cl2?
Is that NaCl or NOCl added? Adding NaCl shouln't change anything.
