Hi, Write an equilibrium expression for chemical equation involving one or moresolid or liquid reactants or products, thanks. CO32-(aq)+ H2O(l) <-----> HCO3-(aq) + OH-(aq)

QUESTION 4 For the following system at equilibrium, predict whether the reaction will shift to the right, left, or not be affected by a decrease in temperature. Also, determine the value of the equilibrium constant increase or decreases.  PCl5(g) ⇌ PCl3(g) + Cl2(g)  endothermic       The reaction will shift to the left and the K value will increase.     The reaction will shift to the right and the K value will decrease.      The reaction will not be affected and the K value does not change.      The reaction will shift to the left and the K value will decrease.     The reaction will shift to the right and the K value will increase.
