A 1.00 L flask was filled with 2.00 mol gaseous sulfur dioxide and 2.00 mol gaseous nitrogen dioxide and heated. After equilibrium was reached, it was found that 1.30 mol gaseous nitrogen monoxide (nitric oxide)was present. The other product formed in the reaction is sulfur trioxide. Calculate the value of the equilibrium constant , Kc, for this reaction.
