Activity 1: Thermodynamic Calculations

Calculate the Gibbs free energy change (ΔG) for the following reactions using the given enthalpy (ΔH) and entropy (ΔS) values. Use the equation ΔG = ΔH - TΔS, where T is the temperature in Kelvin. Assume T = 298 K.

1. ΔH = -100 kJ/mol, ΔS = 200 J/mol·K ______
2. ΔH = 50 kJ/mol, ΔS = -150 J/mol·K ______
3. ΔH = -200 kJ/mol, ΔS = 100 J/mol·K ______

Activity 2: Equilibrium Constant Calculations

For the reactions below, calculate the equilibrium constant (Kc) using the given concentrations. Use the formula Kc = [products]/[reactants], and ensure to balance the equations before calculating.

1. A + B ⇌ C; [A] = 0.5 M, [B] = 0.5 M, [C] = 1.0 M ______
2. D ⇌ E + F; [D] = 0.2 M, [E] = 0.6 M, [F] = 0.6 M ______
