calculate the amount of fructose 6 phosphate formed from glucose 6 phosphate in a 10 milliliter incubation system if 0.5M G6P is incubated overnight at 25C and the equilibrium constant is 0.67.
Equilibrium constants do not provide rate data. They may want you to assume that chemical equilbrium is established overnight, and assume a unimolecular process, with equilibrium constant K.
