Question

The precise ingredients in coke are trade secret, but from the nutritional information on a bottle of coke, we can see that the most important ingredient is sugar: 10.6g per 100 ml. For the purposes of this question, you can model coke as a %u2018dilute%u2019 solution of fructose (C6H12O6) dissolved in water.

Describe what you could do to the bottle of coke to return the Gibbs free energy of the coke solution back to that of pure water. (Your method should not involve separating out the sugar from the water)

Explanation / Answer

Gibbs free energy is given as

G = H - T*S

on adding sugar to water ,

The evaporation process will become more difficult..

The lower the gibbs free energy the easire wil be the reation..

as addition of sugar make the reaction difficult , so gibbs energy is increasing.....

So, to reduce it back to level of water , temperature can be increased ... wihich will decrease the gibbs energy according t ..

G = H - T*S
