Which of the following statements about equilibrium expressions and equilibrium constants are correct? Choose all that apply. Check all that apply. For chemical reactions in which all reactants and products are gases, K. can never be equal to K The equilibrium expression for a reaction involving only gases can be written in terms of either partial pressures or concentrations. A homogeneous equilibrium is one where all reactants and products are in the same physical state, When a chemical reaction is...
