Question

Calculate Δ_rG at 298 K under the conditions shown below for the following reaction: CaCO₃(s) → CaO(s) + CO₂(g) Δ_rG° =+131.1 kJ mol^-1 P(CO₂) = 0.033 atm

Quizplus · Accepted Answer

The reaction Gibbs free energy change ΔrG can be calculated using the equation ΔrG = ΔrG° + RT ln(Q), where Q is the reaction quotient. Here, Q = P(CO2) = 0.033 atm. Using R = 8.314 J/mol·K and T = 298 K, ΔrG = 131.1 kJ/mol + (8.314 J/mol·K * 298 K * ln(0.033)) = 131.1 kJ/mol - 8.5 kJ/mol = 122.6 kJ/mol.
