Phosphoglucoisomerase interconverts glucose 6‑phosphate to, and from, glucose 1‑phosphate. glucose 6 - phosphate phosphoglucoisomerase ⇌ glucose 1 - phosphate glucose 6-phosphate⇌ 1-phosphate After mixing equal amounts of the two molecules, the solution achieved equilibrium at 25 ∘ C . 25 ∘C. The concentration at equilibrium of glucose 1‑phosphate is 0.01 M, 0.01 M, and the concentration at equilibrium of glucose 6‑phosphate is 0.19 M. 0.19 M. Calculate the equilibrium constant, K eq , Keq, and the standard free energy change, Δ G ∘ , ΔG∘, of the reaction mixture.

The equilibrium constant of the reaction is 0.0526 and standard Gibbs free energy of the reaction is -7.296 kJ/mol

Explanation:

For the given chemical equation:

The expression of for above equation follows:

We are given:

Putting values in above expression, we get:

The equation used to calculate standard Gibbs free energy of the reaction follows:

where,

= Standard Gibbs free energy

R = Gas constant = 8.314 J/K mol

T = Temperature =

= Equilibrium constant of the reaction = 0.0526

Putting values in above equation, we get:

Hence, the equilibrium constant of the reaction is 0.0526 and standard Gibbs free energy of the reaction is -7.296 kJ/mol
