A catalyst :

∙

does not change

Δ G

for a reaction.

∙

acts by increasing the rate of forward reaction and backward reaction by equal amounts.

∙

does not affect the value of equilibrium constant.

∙

may have a molecular weight as low as 1 or higher than 200,000.

∴

The only correct choice is that a catalyst may have a molecular weight as low as 1 or higher than 200,000.
