WebThe first law of thermodynamics relates the change in the internal energy of a system (ΔE) to the heat transferred (q) and the work done (w). At constant pressure, q is equal to the change in enthalpy (ΔH) for a process. If ΔH is positive, the process absorbs heat from the surroundings and is said to be endothermic. WebNov 15, 2007 · Reaction (1) is given by: 2*Reaction(2) - Reaction(3) and so: Delta G°(1) = 2*Delta G°(2) - Delta G°(3) Now you use the equation: Delta G° = -nF*Delta E° where n is the number of electrons of the reaction, so you have:-10F*Delta E°(1) = 2*[-6F*Delta E°(2)] - [-2F*Delta E°(3)] 10*Delta E°(1) = 12*Delta E°(2) - 2*Delta E°(3) Delta E ...
