Question 18
H

The pressure on the equilibrium mixture shown is increased at a constant temperature.

H2(g)+I2(g)⇌2HI(g)\text{H}_2\text{(g)} + \text{I}_2\text{(g)} \rightleftharpoons 2\text{HI(g)}H2​(g)+I2​(g)⇌2HI(g)

What is the effect on the amount of hydrogen iodide at equilibrium?

[1]
A

It increases, because the gases are held in a smaller volume

B

It decreases, because there are more molecules on the right

C

It does not change, because both sides have the same number of molecules

D

It increases, because the molecules collide more frequently
