Calculate the value of ()Go for the following reaction , given the standard free energies of formation listed below each ion.

Ag(SO3)_2^3- -> Ag+ + 2SO32-

delta Gf, kJ/mol = -943 +77 -497

a. - 1860 kJ b. – 128 kJ c. + 26 kJ d. - 369 kJ e. + 523 kJ

is this correct?
(1 x -943) - (2 x -497) + 77
-943 - 917 = -1860 so A?
