1a. How does a catalyst change the equilibrium of a
reaction?
r
A catalyst lowers the activation energy and so changes the rate
constants and therefore changes the equilibrium constant.
A catalyst lowers the activation energy and so changes the rate
constants and therefore changes the equilibrium constant.
A catalyst helps to form more products so it always increases
the equilibrium constant.
A catalyst adds a reactant to the equilibrium expression and so
changes the equilibrium constant.

“Catalyst” “The hydration of sucrose into glucose and fructose is catalyzed by acid. The addition of HCl makes the reaction sufficiently fast for us to measure its rate constant. Now imagine doing this experiment without the addition of HCl: how will this change the activation energy, Ea, of the reaction?
