Chapter 6, Problem 5RE

RECALL For the reaction of glucose with oxygen to produce carbon dioxide and water,

$\text{Glucose}+6{\text{O}}_2\to 6{\text{CO}}_2+6{\text{H}}_{\text{2}}\text{O}$

the $DG°$ is 22880 kJ mol^-1, a strongly exergonic reaction. However, a sample of glucose can be maintained indefinitely in an oxygen-containing atmosphere. Reconcile these two statements.
