Paragraph: If a cell has cell potential ' E ' and standard cell potential ' E^0 ', then free energy change of cell process may be calculated as, G=-W=-n F E and G^ =-W_ =-n F E^ Where ' n ' is the number of electrons involved in overall all process. According to Gibs-Helmholtz equation: aligned G & = H - T S G & = H + T ( d G dT )_P aligned Temperature coefficient of cell ' ' will be equal to ( d E d T )_P Question:
