Question

1. Glucose (C6H12O6) is the primary source of metabolic energy forvertebrates.

   1. Write a balanced chemical reaction for the combustion ofglucose. The products of the combustion are carbon dioxide andliquid water.

   2. Using tabulated Gfo values, calculate the free energy ofreaction for the combustion of glucose.

   3. A normal human body requires approximately 2000 kJ of energy tosustain itself. Assuming that glucose is the primary source ofmetabolic energy, how many grams of glucose must be consumed inorder to provide 2000 kJ of energy?

   4. The metabolism of glucose in vertebrate systems requires anumber of steps, which when added together result in the reactionfrom part (a). Explain why it is possible to calculate themetabolic energy even though there is more than one step in theprocess.

2. Write reactions that correspond to the following changes.

   1. Gof for solid Aluminum oxide

   2. the standard free energy of combustion of liquid ethanol,C2H5OH(l).

   3. the standard enthalpy of neutralization of barium hydroxidesolution by aqueous hydrochloric acid.

   4. Gof for gaseous vinyl chloride, C2H3Cl(g)
