Question

28. Anhydrous calcium chloride is often used as a
desiccant. In the presence of excess of CaCl, the
amount of the water taken up is governed by K =
6.4 x 1085 for the following reaction at room temperature,
CaCl,(s) + 6H2O(g) + CaCl2.6H2O(s). What is the
equilibrium vapour pressure of water in a closed vessel
that contains CaCl,(s)?
(a) 5 x 10-13 atm (b) 5 x 10-15 atm
(c) 5 x 10-12 atm (d) 5 x 10-11 atm
