A mixture of hydrogen gas, neon gas, and chlorine gas were stored in a 5 L flask at a constant temperature of 250K. Which of these gases would have the greatest average kinetic energy?
Group of answer choices
Neon gas has the greatest average kinetic energy.
Fluorine gas has the greatest average kinetic energy.
It is impossible to determine the relative kinetic energy without knowing the pressure and volume of each gas.
Hydrogen gas has the greatest average kinetic energy.
They all have the same average kinetic energy.
