Question
A mixture of ethane and propanol gases is maintained at a temperature of 400 K. Which of the following best compares the average kinetic energy and the average molecular speed of the ethane molecules with those of the propanol molecules?
The average kinetic energy of the ethane molecules is equal to that of the propanol molecules, and the average speed of the ethane molecules is less than that of the propanol molecules.
The average kinetic energy of the ethane molecules is equal to that of the propanol molecules, and the average speed of the ethane molecules is greater than that of the propanol molecules.
The average kinetic energy of the ethane molecules is greater than that of the propanol molecules, and the average speed of the ethane molecules is greater than that of the propanol molecules.
The average molecular speeds of ethane and propanol cannot be compared without knowing the total pressure of the gas mixture.
