1. the pressure inside a pressure cooker is 2.0 atm. how many minutes will it take to cook 1.0 pound of potatoes in a pressure cooker if it takes 45 minutes to cook them in boiling water at standard pressure? given: volume of the pressure cooker is 4.0l, there are 0.25 gaseous moles, and e_a = 1.77 x 10^5 5 j/mol.
2. at 320°c, the half-life for the first-order decomposition of so_22cl_22 is 8.75 hrs. if the initial pressure of so_2cl_2 is 791 torr inside a 1.25 l container, how many molecules will remain after 14.5 hrs? use “e” for scientific notation.
