Question 20

A chemist is selecting operating conditions for a reversible gas reaction that produces compound Z. The forward reaction is exothermic. The product side has more gas molecules than the reactant side.

What combination of changes would increase the equilibrium yield of Z?

[1]
A

A decrease in temperature and a decrease in pressure

B

A decrease in temperature and an increase in pressure

C

An increase in temperature and a decrease in pressure

D

An increase in temperature and an increase in pressure
