Answer to Question #230582 in General Chemistry for Ory

Question

Consider the equilibrium 2I(g) Δ I2(g) What would be the effect on the position of equilibrium of (a) increasing the total pressure on the system by decreasing its volume; (b) adding gaseous I2 to the reaction mixture; and (c) decreasing the temperature at constant volume?

Answer 1

Solution: Decreasing the volume leads to an increase in pressure which will cause the equilibrium to shift towards the side with fewer moles.

adding gaseous I2 to the reaction would shift equilibrium to the left

Pressure would decrease
