17. The EMF of the Pt,H2|NaOH(aq)|Bi2O3,Bi circuits at 291 K is equal to 0.3846 V. The temperature coefficient of the EMF is dE/dT=-3.9*10-4 V/K. Calculate the heat of formation of 1 mole of Bi2O3(solid) from elements at 291 K and pH2=1, if the heat of formation of liquid water from elements under the same conditions is (-286.18) kJ/mol.
