Question

Calculate ΔG_rxn at 298 K under the conditions shown below for the following reaction. SO₃(g)+ H₂O(g)→ H₂SO₄(l)ΔG°= -90.5 kJ P(SO₃)= 0.20 atm,P(H₂O)= 0.88 atm

Quizplus · Accepted Answer

To calculate ΔG_rxn, use the equation ΔG = ΔG° + RT ln(Q), where Q is the reaction quotient. Here, Q = P(SO3) * P(H2O) = 0.20 * 0.88. Plugging in the values, ΔG = -90.5 kJ + (8.314 J/mol*K * 298 K * ln(0.176)) = -86.2 kJ.
