If the K_sp of AgI is 1.5 × 10^-16 at 298 K,what is ΔG_r° for the reaction of Ag⁺(aq)with I^-(aq)under standard conditions at 298 K.

Question

Quizplus · Accepted Answer

The standard Gibbs free energy change (ΔG°) can be calculated using the equation ΔG° = -RT ln K, where R is the gas constant (8.314 J/mol·K), T is the temperature in Kelvin (298 K), and K is the equilibrium constant (Ksp in this case). Substituting the given values, ΔG° = - (8.314 J/mol·K)(298 K) ln(1.5 × 10^-16) = -90.3 kJ/mol.
