The enthalpy of evaporation of water at ...

The enthalpy of evaporation of water at 373 K is 40.67 kJ`"mol"^(-1)`. What will be the enthalpy of evaporation at 353 K and 393 K if average molar heats at constant pressure in this range for water in liquid and vapour states are 75.312 and 33.89 `JK^(-1)"mol"^(-1)` respectively?

Text Solution

Verified by Experts

The correct Answer is:
`%` of `CH_(4) = 74.5%`
`%` of `C_(2)H_(5)=25.5%`
