WebMetabolic rate. The amount of energy expended by an animal over a specific period of time is called its metabolic rate. Metabolic rate may be measured in joules, calories, or kilocalories per unit time. You may also see metabolic rate given as oxygen consumed (or carbon dioxide produced) per unit time. Web2 de fev. de 2024 · The rate of a chemical reaction is measured by the equation of change in concentration divided by time. This equation produces the units of Molarity/second or Molarity/minute.
