n=no. of moles of electrons exchanged during the section
for reversible cell reaction `d(/_\G)=(/_\_rV)dp-(/_\_rS),dT`
at constant pressure `d(/_\G)=-(/_\_rS).dT`
:' At constant pressure `/_\G=/_\H-T./_\S`
:. /_\G=/+\H+T(d(/_\G))/((dT)_P)`
`((dE_(cell))/(dT))_P` is known as temperture coefficient of the e.m.f of the cell.
At 300 k, `/_\` H for the reaction
`Zn(s)+AgCl(s)toZnCl_2(aq)+2Ag(s)` is
-218 KJ/mol while the e.m.f of the cell was 1.015V. `((dE)/(dT))_p` of the cell is :
