The equilibrium constant ( left(mathrm{K}_{mathrm{C}}right) ) for the give reaction is: [ begin{aligned} K_{c} &=frac{left[mathrm{SO}_{3}right]^{2}}{left[mathrm{SO}_{2}right]^{2}left[mathrm{O}_{2}right]} &=frac{(1.90)^{2} mathrm{M}^{2}}{(0.60)^{2}(0.821) mathrm{M}^{3}} end{aligned} ] ( =12.239 mathrm{M}^{-1}(text {approximately }) ) Hence, ( K ) for the equilibrium is ( 12.239 mathrm{M}^{-1} )
