Question

Reaction rates and Pressure? Check my reasoning!

8A(g)+5B(g)--->8C(g)+6D(g)

When will the reaction be slower? A. Lower temperatures B. Smaller Volumes C. Higher Pressures D. With a Catalyst E. None of the above

I know it's not D or E, but the other 3 are techically fair game, since it's a gaseous Reaction, correct? The answer given is "A," but a smaller volume or higher pressure would force the equilibrium to the side with less moles, which is the reactants. Is my reasoning correct
