Question: What is the relationship between ΔG and the equilibrium constant (K)?

Options:

Correct Answer: ΔG = -RT ln(K)

Solution:

The relationship is given by ΔG = -RT ln(K), where R is the gas constant and T is the temperature in Kelvin.

What is the relationship between ΔG and the equilibrium constant (K)?

What is the relationship between ΔG and the 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 that connects ΔG and K: ΔG = -RT ln(K).
Step 4: Identify R as the gas constant, which is a specific value used in calculations.
Step 5: Recognize that T is the temperature measured in Kelvin.
Step 6: Realize that if K is greater than 1, ΔG is negative, indicating the reaction favors products.
Step 7: Conversely, if K is less than 1, ΔG is positive, indicating the reaction favors reactants.
