Which of the following statements is TRUE? a) Particles of different masses have the same average speed at a given temperature.
b) The larger a molecule, the faster it will effuse. c) At very high pressures, a gas will occupy a larger volume than predicted by the ideal gas law. d) For a given gas, the lower the temperature, the faster it will effuse. e) None of the above statements are true
According to Graham's law, the effusion rate and the square root of the molecular mass of a gas are inversely proportional. Therefore, heavy gas particles diffuse slower compared to light particles which effuse at a faster rate.
Particles of different masses have varying average speeds at a given temperature. Large molecules effuse at a slower rate compared to smaller molecules.
The diffusion rate of a gas increases with an increase in temperature because higher temperature increases the kinetic energy of particles of the gas making them move faster.
