Transcribed Image Text:
Your stomach is a chemical reactor. When you devour a fast food 99c special hamburger in about a minute, it acts like an instantaneous input of 325 g of food entering the stomach. In response, the stomach starts producing gastric liquids (acids), which are continuously excreted into the stomach at the rate of 12 mL/min as the hamburger is digested. The fluid also leaves the stomach to the small intestine at the rate of 12 mL/min, so the volume of liquid in the stomach stays constant at 1.15 L. The hamburger digestion rate constant is 1.33/hr. (a) What kind of ideal reactor would you model your stomach as? (b) What fraction of the hamburger's mass will remain undigested in your stomach 1 hour after you eat the hamburger?
