The water in a pressure cooker boils at a temperature greater than 100°C because it is under pressure. At this higher temperature, the chemical reactions associated with the cooking of food take place at a greater rate. (a) Some food cooks fully in 10.0 min in a pressure cooker at 120.0°C and in 40.0 minutes in an open pot at 100.0°C. Calculate the average activation energy for the reactions associated with the cooking of this food. kJ mol! (b) How long will the same food take to cook in an open pot of boiling water at an altitude of 8000 feet, where the boiling point of water is 91.9 °C? min
