chem1220:
Free-energy change, delta G degree, is related to cell potential, E degree, by the equation delta G degree = -nFE degree where n is the number of moles of electrons transferred and F = 96, 500 C/(mol e^-) is the Faraday constant. When E degree is measured in volts and can be determined from half-reaction potentials as given in the table below. delta G degree must be in joules since 1 J = 1 C middot V. Since E degree is positive and delta G degree is negative, this reaction is spontaneous under standard conditions. Calculate the standard cell potential at 25 degree C for the reaction X(s) + 2Y^+ (aq) rightarrow X^2+ (aq) + 2Y(s) where delta H degree = -847 kJ and delta S degree = -391 J/K. Express your answer numerically in volts. E degree =
