Question

Be sure to answer all parts. Three 8−L flasks, fixed with pressure gauges and small valves, each contain 5 g of gas at 273 K. Flask A contains He, flask B contains H2, and flask C contains CH4. Rank the flask contents in terms of: (a) pressure. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B = C (b) average molecular kinetic energy. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B = C (c) diffusion rate after valve is opened. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B = C (d) total kinetic energy of the molecules. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B = C (e) density. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B = C (f) collision frequency. A > B > C A > C > B B > C > A B > A > C C > B > A C > A > B A = B = C
