If the enzyme phosphohexoisomerase is added to a 0.3 M solution of fructose 6-phosphate, and the reaction is allowed to proceed to equilibrium, the final concentrations are 0.2 M glucose 6-phosphate and 0.1 M fructose 6-phosphate. These data give an equilibrium constant of 2. What is the equilibrium constant if the initial concentration of fructose 6-phosphate is 3 M?

Question

Quizplus · Accepted Answer

The equilibrium constant (K) is a ratio of the concentrations of products to reactants at equilibrium and is independent of the initial concentrations. Therefore, the equilibrium constant remains 2 regardless of the initial concentration of fructose 6-phosphate.
