Which of the following statements accurately compares the rates of motion of nitrogen (N 2 ) gas molecules and Helium (He) gas atoms at the same temperature. Use Graham's Law to solve the problem. A. At the same temperature, nitrogen molecules will travel at a rate approximately 2.6 times faster than helium atoms .
B. At the same temperature , helium atoms will travel at a rate approximately 2.6 times faster than nitrogen molecules.
C. The helium atoms will move at a rate approximately 1.9 times faster than nitrogen molecules at the same temperature .
D. Being at the same temperature means the average kinetic energy is the same , so the average rate of motion of the helium atoms and nitrogen molecules will be the same
