Answer #1

(NH4)2SO4(s)→2NH3(g)+H2O(l)+SO3(g)

ΔG∘rxn = ΔG∘f products - ΔG∘f rectants

              = -371.06-237.13 + 2*-16.45 -(-901.9)

                = 260.81KJ/mole   = 260810J/mole

ΔG∘rxn   = -RTlnK

260810   = -8.314*298*2.303logK

260810   = -5705.84logK

logK        = 260810/-5705.84

logK         = -45.7

K            = 10^-45.7   = 2*10^-46 >>>>answer
