What is the relationship between ΔG and equilibrium constant K?

Step 1: Understand that ΔG represents the change in free energy of a reaction.
Step 2: Know that K is the equilibrium constant, which tells us the ratio of products to reactants at equilibrium.
Step 3: Learn the formula ΔG = -RT ln K, where R is the gas constant (approximately 8.314 J/(mol·K)) and T is the temperature in Kelvin.
Step 4: Realize that if K is greater than 1, ΔG is negative, indicating the reaction favors products.
Step 5: If K is less than 1, ΔG is positive, indicating the reaction favors reactants.
Step 6: If K equals 1, ΔG is zero, meaning the system is at equilibrium.
