Study Notes
Equilibrium Constant
- The equilibrium constant (Keq) is a value that describes the ratio of products to reactants at equilibrium.
- It indicates the extent to which a reaction proceeds to completion.
- A higher Keq value suggests that more products are formed at equilibrium, while a lower Keq indicates a preference for reactants.
Glucose-6-Phosphate Isomerisation
- The isomerisation of glucose-6-phosphate (G6P) to fructose-6-phosphate (F6P) has an equilibrium constant (Keq) of 0.428 at 25 °C.
Calculating F6P Concentration at Equilibrium
- To calculate the concentration of F6P at equilibrium, we need to consider the initial concentration of G6P and the Keq value.
- Given an initial G6P concentration of 0.1 M, we can use the Keq expression to solve for the F6P concentration:
- Keq= [F6P]/[G6P].
- We need to consider that F6P molecules are formed from G6P molecules.
