Zn(s)+2AgCl(s) hArr ZnCl_(2) (0.555 M)+2Ag(s) E_(0^(@)C)=1.015" volt"((dE)/(dT))_(P)=-4.02xx10^(-4) volt per degree. Find DeltaG, DeltaS

Answer»

<P>

SOLUTION :We KNOW that,
`DeltaH=nF [T((dE)/(dT))_(P)-E]`
`=2xx96500 [-273xx4.02xx10^(-4)-1.015]`
`=-217075.98" joule"=-217.075 KJ`
`DeltaG=-nFE=-2xx96500xx1.015=-195895 J`
`=-195.895 kJ`
`DeltaG=DeltaH-TDeltaS`
`-195.895=-217.075-273xxDeltaS`
`DeltaS=-0.07758 kJ =-77.58 J=-18.55` CAL
