Question

Consider three identical flasks with different gases:
Flask A: CO at 760 torr and 273 K
Flask B: $ ext{N}_2$ at 250 torr and 273 K
Flask C: $ ext{H}_2$ at 100 torr and 273 K
In which flask will the molecules have the greatest average kinetic energy per mole?

Prashant Kotian · Accepted Answer

Correct answer: D. KE per mole is 3/2 RT. Since T is 273K for all, it is the same. Therefore, correct answer is D.
