- What is the value of ΔG∘ at 298 K?
Express your answer to four significant figures and include the
appropriate units.
- What is the value of K at 298 K?
Express your answer using two significant figures.
(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
