7.2. What is Kc for the following equilibrium when the equilibrium concentration of each substance is: [SO2] = 0.60M, [O2] = 0.82M and [SO3] = 1.90 M?
2SO2(g) + O2(g) ? 2SO3(g)

KC= [SO3]2 / [SO2]2 [O2]
= (1.90)2 / (0.60)2 (0.82)
= 12.229 L mol-1

<p><strong>7.1. A liquid is in equilibrium with its vapour in a sealed container at a fixed temperature. The volume of the container is suddenly increased.</strong></p>
<p><strong>(a) What is the initial effect of the change on the vapour pressure? </strong></p>
<p><strong>(b) How do the rates of evaporation and condensation change initially? </strong></p>
<p><strong>(c) What happens when equilibrium is restored finally and what will be the final vapour pressure?</strong></p>
