1. What happens to the value of the equilibrium constant for a reaction if the reaction equation is reversed? Multiplied by a constant?
2. What is the effect of a change in volume on a chemical reaction (that includes gaseous reactants or products) initially at equilibrium?
3. What is the effect of a temperature change on a chemical reaction initially at equilibrium? How does the effect differ for an exothermic reaction compared to an endothermic one?
