c) The pathway for a reaction is the same in the presence of a catalyst as in its absence, but the rate constants are decreased in both the forward and the reverse directions.
d) A catalyst must be carefully chosen to shift the equilibrium toward the products.

Decide which are true, and if the statement is false explain why. I don't get these last two problems, could someone explain to me how to figure this out?

For C, I believe its true because a catalyst just lowers the activation energy but it does not change the pathway.
