help me please!

H-C-OH 3. Let's now consider a slightly different reaction, a reaction in solution: Glucose (aq) Fructose (aq) CHOH Glucose Fructose 0.0 Ho CH,OH HC I .. I-OH --OH 11-OH H-OH CH, OH CH OH OH D-Glucose D-Fructose Someone determined that this conversion has 4 G=+1.7kJmol' in aqueous solution. a) Determine equilibrium constant K for this reaction based on AG value. OH HO HO OH CH,OH OH b) Give the expression of the equilibrium constant K in terms of the concentration of glucose and fructose in the solution. What kind of reference states do you assume for the two solutes here
