Question 1
A sample of oxygen gas is collected over water at 23 °C at a barometric pressure of 751 mmHg (the vapor pressure of water at 23 °C = 21 mmHg). The partial pressure of oxygen gas in the sample collected is ________.
◦ 0.96 atm
◦ 21 mmHg
◦ 751 mmHg
◦ 1.02 atm
◦ 44 mmHg
Question 2
According to the kinetic-molecular theory of gases:
◦ gaseous particles are in constant, nonlinear motion
◦ at constant temperature, all particles have equal translational kinetic energy
◦ the faster a given particle is moving, the greater its translational kinetic energy
◦ at constant temperature, average kinetic energy is a function of gas volume
◦ all interparticle collisions are completely inelastic
