Question 1

2 and NH
3 are allowed to effuse through a porous membrane under identical conditions, the rate of effusion for NH
3 will be ________ times that of CO.
◦ 0.39
◦ 0.62
◦ 1.6
◦ 2.6
Question 2
If gas volume is doubled but the temperature remains constant:
◦ the pressure stays the same
◦ the molecules move faster
◦ the final pressure is twice the pressure before the volume change.
◦ the molecules move slower
◦ the final pressure is 1/2 of the pressure before the volume change.
