For reaction, Ag₂CO₃ (s) ⇌ Ag₂O (s) + CO₂ (g), the ∆Hº = 79.14 kJ/mol, ∆Sº = 167.2 J/K.

Determine the equilibrium constant at which the temperature is 365.1 K.

Consider a hypothetical reaction at 38 ºC, X₂ (aq) + 2 Y (s) ⇌ 3 Z (aq), with a ∆G of −75.8 kJ.

Concentrations of reactants and products: [X₂] = 1.4 M, [Y] = 0.34 M, [Z] = 2.6 M. Calculate K_eq of the reaction under standard conditions.

Consider the sublimation of iodine at 25.0 °C : I2(s) ¡ I2( g) b. Find ΔG rxn at 25.0 °C under the following nonstandard conditions: i. PI2 = 1.00 mmHg ii. PI2 = 0.100 mmHg
