Nitrogen dioxide can be formed fromnitrogen oxide and oxygen: <?xml:namespace prefix = o ns ="urn:schemas-microsoft-com:office:office" />

2NO (g) + O2 (g) <- -> 2NO2 (g)

At 1000K, the equilibrium constant Kc is1.20.

A system of NO,O2 and NO2 is analyzed andthe following concentrations are found: [O2]=1.25M [NO]=2.25M[NO2]=3.25M

Is the system at equilibrium with respect to the reaction above?If not, will the concentration of NO2 increase, decrease, or willthe system proceed to equilibrium?
