my teacher wrote this equation under the title "thermodynamical approach of electrochemical cell" and i couldnt figure out how she wrote that. i only know ΔG=ΔH-TΔS. -ΔH is decrease in heat content at constant pressure. she then wrote ΔnFE= -ΔH + T{δ(nFE)/δT }p . this 'p' is used to denote 'at co...
