Using the concepts of chemical kinetics, explain why food kept in the refrigerator or freezer does not spoil as quickly as food kept at room temperature. Address the effect of temperature on the microorganisms, but base your comments on chemical kinetics. Compare the behavior of frozen microorganisms that are later warmed up to that of humans treated in the same manner.
