The reaction 2NO + Cl2 <==> 2NOCl has Kc= 210 what is the equilibrium concentration of NO in moles per liter given the following Cl2= .46 NOCl= .43M at equilibrium.

So far all ive gotten is
210= [.43]^2/[.46][NO]^2

where do I go from here please

• Chemistry -

The equation you have written can be solved for [NO]at equilibrium. Just use some algebra to rearrange it. You will need to take a square root of [NO]^2.
