A large portion of metabolic energy arises from the biological combustion of
glucose:
$$\mathrm{C}_{6} \mathrm{H}_{12} \mathrm{O}_{6}(s)+6 \mathrm{O}_{2}(g)
\longrightarrow 6 \mathrm{CO}_{2}(g)+6 \mathrm{H}_{2} \mathrm{O}(g)$$
(a) If this reaction is carried out in an expandable container at \(37^{\circ}
\mathrm{C}\) and \(780 .\) torr, what volume of \(\mathrm{CO}_{2}\) is produced
from \(20.0 \mathrm{~g}\) of glucose and excess \(\mathrm{O}_{2} ?\)
(b) If the reaction is carried out at the same conditions with the
stoichiometric amount of \(\mathrm{O}_{2}\), what is the partial pressure of
each gas when the reaction is \(50 \%\) complete \((10.0 \mathrm{~g}\) of glucose
remains)?
