Write the equilibrium-constant expression for the reaction shown in terms of [SO2] , [CO2] , [CS2] , and [O2] . 2SO2(g)+CO2(g)↽−−⇀CS2(g)+3O2(g)

c , which is sometimes symbolized as or eq , denotes that the equilibrium constant is expressed using molar concentrations. For this question, c means the same thing as and eq .
