Question
I have to find Kc for the reaction. Thank you!
Openvellum.ecollege.com <Chapter 15 HW + Calculating Equilibrium Constants The equilibrium constant, K, of a reaction at a particular temperature is determined by the concentrations or pressures of the reactants and products at equilibrium. For a gaseous reaction with the general form aA+bB cC + dD the Ke and K, expressions are given by Kc = [CD] [A]ª[B] (Pc) (Pb)d (PA)" (PB) K₂ The subscript c or p indicates whether K is expressed in terms of concentrations or pressures.
