1.	10 moles of a liquid L are 50% converted into its vapour at its boiling point (273^@C) and at a pressure of 1 atm.If the value of latent heat of vapourisation of liquid L is 273 L atm/mole , than which of the following statements is/are correct : Assume volume of liquid to be negligible and vapour of the liquid to behave ideally.
Answer» Work done by the system in the above process is 224 L atm The enthalpy change `(DELTAH)` for the above process is 1365 L atm (with respect to magnitude only) The ENTROPY of the system increases by 2.5 L atm in the above process The value of `DeltaU` for the above process is 1589 L atm. Solution :`V_f=5xxRxx546=224 L` `W=-P_(ext)(DeltaV)=-1` atm (224 L) =-224 L atm `:.` work done by system =224 L atm Enthalpy change `(DeltaH)=q=273xx5=1365 L atm` `DeltaS=(DeltaH_(VAP))/T=1365/546=2.5` L atm /K `DeltaU=q+W=1365-224=1141 L atm`
