For the gas equilibrium CO(g) + 2H2(g) ? CH3OH(g), what is the effect of increasing total pressure (by decreasing volume) on the position of equilibrium?
Which change will both increase the rate and increase the extent (yield) of an endothermic forward reaction?
Which change will increase the extent of a reaction that is endothermic in the forward direction?
Which statement about a catalyst is correct?
Which description correctly distinguishes rate and extent of reaction?
For the equilibrium A(g) ? B(g) + C(g), which operation will change the equilibrium constant K?
If an equilibrium is endothermic in the forward direction, what will happen to K when temperature is raised?
Which statement about catalysts and equilibrium is false?
When the concentration of a reactant is increased in a dynamic equilibrium, what immediate effect occurs?
Which experimental action would change the rate but not the equilibrium position for a closed heterogeneous system?
