Chapter 4, Problem 4.20E

When a person performs work, it is non- $pV$ work. Energy to do work typically comes from the metabolism of glucose in the cells:

${\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}\left(\text{s}\right)+6{\text{O}}_{\text{2}}\left(\text{g}\right)\to {\text{6CO}}_{\text{2}}\left(\text{g}\right)+6{\text{H}}_{\text{2}}\text{O}\left(l\right)$

If jogging involves $2090\text{kJ}$ of work per hour, how much time is needed to burn off $120\text{g}$ of glucose, a typical amount in a medium candy bar?
