A.                 \[{{K}_{c}}=\frac{[2NOCl]}{[2NO]\,[C{{l}_{2}}]}\]              
B.                 \[{{K}_{c}}=\frac{{{[NOCl]}^{2}}}{{{[NO]}^{2}}[C{{l}_{2}}]}\] 
C.                 \[{{K}_{c}}=\frac{{{[NOCl]}^{2}}}{[NO]{{[C{{l}_{2}}]}^{2}}}\]        
D.                 \[{{K}_{c}}=\frac{{{[NOCl]}^{2}}}{{{[NO]}^{2}}{{[C{{l}_{2}}]}^{2}}}\]
Answer» C.                 \[{{K}_{c}}=\frac{{{[NOCl]}^{2}}}{[NO]{{[C{{l}_{2}}]}^{2}}}\]
