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...
