A 1.07 mol sample of Ar gas is confined in a 25.2 liter container at 12.3 degrees celcius. If the amount of gas is decreased to 0.535 mol, holding the volume and temperature constant the pressure will decrease because: (select all that apply) a. With lower average speeds, on average the molecules hit the walls of the container with less force. b. With fewer molecules in the container, the molecules have lower average speeds. c. With fewer molecules per unit volume, the molecules hit the walls of the container less often d. As the number of molecule- wall collisions increases, the force per collision decreases e. None of the above
