Question 14
H

For A(g)+B(g)⇌C(g)+D(g)\mathrm{A(g)+B(g)\rightleftharpoons C(g)+D(g)}A(g)+B(g)⇌C(g)+D(g), increasing pressure has little effect on position because

[1]
A

there are equal numbers of gas molecules on each side

B

all four substances are gases, so pressure cancels out

C

pressure only affects reactions that involve solids

D

the forward reaction is irreversible at high pressure
