5. Which one of the following statements is correct? (A) For a 1.0-L container of neon gas at STP, its frequency of collision with the container walls will increase when the temperature is decreased to -50°C. (B) Real gas behaves most ideally when a container volume is relatively small and the gas molecules are moving relatively slow. (C) For separate 1.0-L gaseous samples of H2, Xe, Cl2 and O2 all at STP, H2 has the highest average velocity. (D) For separate 1.0-L gaseous samples of H2 and O2 that all have the same average velocity, O2 has a lower temperature. (E) For separate 1.0-L gaseous samples of H2, Xe, Cl2 and O2 all at STP, Xe has the highest average kinetic energy.
