Calculate the temperature at which liquid water will be in equilibrium with water vapour.
`Delta_(vap)H = 40.00 kJ mol^(-1)` and `Delta_(vap)S = 0.100 kJ mol^(-1)K^(-1)`

Text Solution

Verified by Experts

Given, `DeltaH = 40.00 kJ mol^(-1)`
`DeltaS = 0.100 kJ mol^(-1) K^(-1)` and `DeltaG =0`
Applying `DeltaG = DeltaH - T DeltaS`
`0 =40.00 - T xx 0.10`
`T = (40.00)/(0.109) = 400.0 K`

Entropy is a measure of randomess of system. When a liquid is converted to the vapour state entropy of the system increases. Entropy in the phase transformation is calculated using Delta S = (Delta H)/(T) but in reversible adiabatic process Delta S will be zero. The rise in temperature in isobaric or isochoric process increases the randomness of system, which is given by Delta S = "2.303 n C log"((T_(2))/(T_(1))) C = C_(P) or C_(V) The temperature at whicgh liquid H_(2)O will be in equrilibrium with its vapour is ( Delta H and Delta S for vapourisation are 50 kJ mol^(-1) and 0.15 kJ mol^(-1)K^(-1) )
