Question

Lactose is broken down into monosacharides in the stomach through the following reaction:

Lactose + H2O ------> Glucose + Galactose

Chemicals:

Lactose-C12H22O11

Glucose-C6H12O6

Galactose-C6H12O6

1) Find the standard heat of the reactio for this conversion

2) The above reaction is usually catalyzed by the enzyme lactase. However, lactose-intolerant people are not able to produce lactase and become ill when they consume too much lactose. Suppose that you hve developed a new treatment for lactose intolerance. To test its effectiveness, you decide to run a simulation using a bioreator. Lactose dissolved in water is added to the bioreactor at a rate of 100g/min. Reation products, water, and undigested lacto,se are removed at the same rate. Assume that reactants and products are both at standard conditions (25C, 1 atm). If 99 J/s heat is removed to keep the bioreactor temperature constant, what percentage of the lactose is broken dow into gluclose and galactose?

Matlab code answer preferred!
