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.

The water in a pressure cooker boils at a temperature greater than 100C 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 5.00min in a pressure cooker at 110.0C and in 20.0min in an open pot at 100.0C. Calculate the average activation energy for the reactions associated with the cooking of this food. (Enter your answer to three significant figures.) kJmol1 (b) How long will the same food take to cook in an open pot of boiling water at an altitude of 15000 feet, where the boiling point of water is 84.4C ? (Enter your answer to three significant figures.) min
