Asked Feb 7, 2019

When the reaction A+BC is at equilibrium, the concentration of the reactants are as follows; [A] = 2mM, [B] = 3mM, and [C] = 9mM. What is the standard free energy change for the reaction?

check_circleExpert Solution
Step 1

The equilibrium reaction and the equilibrium concentrations of the reactants A and B and the product C are given.

Step 2

Use the equilibrium concentrations to determine the equilibrium constant, Kc for the reaction. Kc is defined as the ratio of the concentration(s) of the product(s) raised to their stoichiometric co-efficient and the concentration(s) of the reactant(s), again raised to the stoichiometric co-efficient.
