Which one of the following gases would have the highest average molecular speed at 25 °C? A)O₂ B)N₂ C)CO₂ D)CH₄ E)SF₆

Question

Quizplus · Accepted Answer

The average molecular speed of a gas at a given temperature is inversely proportional to the square root of its molar mass (as per the equation derived from the kinetic molecular theory of gases). Among the given options, CH4 (methane) has the lowest molar mass, which means it would have the highest average molecular speed at 25 °C.
