Problem

At a certain temperature, a 1.00 L1.00\,\text{L} vessel is filled with [SO2]=1.20 M[\text{SO}_2]=1.20\,\text{M}, [O2]=0.80 M[\text{O}_2]=0.80\,\text{M}, and [SO3]=0 M[\text{SO}_3]=0\,\text{M}. For the equilibrium 2SO2(g)+O2(g)⇌2SO3(g)2\text{SO}_2(g)+\text{O}_2(g)\rightleftharpoons2\text{SO}_3(g) the concentration of SO2\text{SO}_2 is measured to be 0.40 M0.40\,\text{M} at equilibrium. What is the equilibrium constant KcK_c at this temperature? a) 2.5 b) 10 c) 1.6 d) 12.5
