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.
