Question

Glucose (C6H12O6) is the primary source of metabolic energy for vertebrates.

Write a balanced chemical reaction for the combustion of glucose. The products of the combustion are carbon dioxide and liquid water.

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

A normal human body requires approximately 2000 kJ of energy to sustain itself. Assuming that glucose is the primary source of metabolic energy, how many grams of glucose must be consumed in order to provide 2000 kJ of energy?

The metabolism of glucose in vertebrate systems requires a number of steps, which when added together result in the reaction from part (a). Explain why it is possible to calculate the metabolic energy even though there is more than one step in the process.

Write reactions that correspond to the following changes.

Gof for solid Aluminum oxide

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

the standard enthalpy of neutralization of barium hydroxide solution by aqueous hydrochloric acid.

Gof for gaseous vinyl chloride, C2H3Cl(g)

Using the figure below, answer the following questions.

Determine the K values for each reaction.

Determine the Gibbs energy for each of the reactions (forward and reverse) at 1000 K.

Explanation / Answer

C6H12O6 + 6O2 ----- 6CO2 + 6H2O
