A 1.72 mol sample of Kr gas is confined in a 40.4 liter container at 13.2 °C. If the amount of gas is decreased to 0.860 mol, holding the volume and temperature constant, the pressure will decrease because: Choose all that apply. As the number of molecule-wall collisions increases, the force per collision decreases. With fewer molecules per unit volume, the molecules hit the walls of the container less often. With lower average speeds, on average the molecules hit the...

Which of the following statements is true for real gases? Choose all that apply Attractive forces between molecules cause a decrease in pressure compared to the ideal gas. Attractive forces between molecules cause an increase in pressure compared to the ideal gas. As molecules increase in size, deviations from ideal behavior become more apparent at relatively low pressures. As attractive forces between molecules increase, deviations from ideal behavior become more apparent at relatively low temperatures. Compute the root-mean-square speed of...

1.Effusion is a process in which a gas escapes from a container through a small opening into a vacuum. In a pair of experiments, a sample of tetrafluoroethylene, C2F4, effuses at a rate of 4.6 × 10-6 mol/h and an unknown gas effuses at a rate of 4.0×10-6 mol/h. Identify the unknown gas. 2.Molecules in a sample of a gas move at a variety of speeds. Molecular speed can be described by the root-mean-square speed of the gas, which is...
