Question

6. The pressure on each of the following systems is increased by decreasing the volume of the container. Explain whether each system would shift left, right, or stay the same.

a. 2 SO2 (g) + O2 (g) ↔ 2 SO3 (g) (1 mark)

b. H2 (g) + I2 (g) ↔ 2 HI(g) (1 mark)

c. CaCO3 (s) ↔ CaO(s) + CO2 (g) (1 mark)

d. AgCl(s) ↔ Ag1+(aq) + Cl1- (aq) (1 mark)

How could you alter the following to make the equilibrium below shift to the left:

2CO(g) + O2(g) 2CO2(g) + 566 kJ

a) [CO]

b) pressure

c) temperature>2NH(G)

Changing the volume of the system alters the equilibrium position of this equilibrium:N2(G)+3H2(G)------ But a similar change has no effect on this equilibrium: H2(G)+ Cl2(G)----> 2HCl (g) Explain
