Calculate the entropy change of a process H_2 O_((f)) toH_2 O_((g)) at

1.	Calculate the entropy change of a process H_2 O_((f)) toH_2 O_((g)) at 373K. Enthalpy of vaporization of water is 40850 J Mole""^(-1)
Answer» SOLUTION :`H_2 O_((l))toH_2 O` temperature`T =373 K` enthalpyof vapourisationof water =` DELTA H_(vap )= 40580jmol^(-1)` `DeltaS ="entropychange"` ` =( Delta H_(vap))/(T_(b)) = ( 40850 )/( 373 )` ` DeltaS` ( entropychange)` = 109.51 J MOL ^(-1)K^(-1) `
