The moisture content of a gas is often expressed in terms of the dew point. The point is the temperature to which the gas must be cooled before the gas becomes saturated with water vapour. At this temperture, water or ice (depending on the temperature) will be deposited on a solid surface. Dew point of `H_(2)O` is `-43^(@)C` at which vapour pressure of ice formed is `0.07 mm`. Assuming that the `CaCl_(2)` owes its desicationg properties to the formation of `CaCl_(2).2H_(2)O`, calculate :
(`i`) `K_(p)` at that temperature of the reaction,
(`ii`) `DeltaG^(@)`
`CaCl_(2(s))+2H_(2)O_((g))hArrCaCl_(2).2H_(2)O_((s))`.
