Chemistry - Ideal Gas Question with Solution | TestHub
Molecules of gases remain in a continuous state of random motion. While moving, they collide with each other and with the walls of the container. This results in a change in their speed and a redistribution of energy. Maxwell and Boltzmann have shown that the actual distribution of molecular speeds depends on the temperature and molecular mass of the gas. Maxwell derived a formula for calculating the number of molecules possessing a particular speed () as:
Maxwell distribution fraction,
Which of the following is INCORRECT conclusion about the gas molecules?
Options:
Answer:
Solution:
According to the Maxwell-Boltzmann distribution, increasing the temperature shifts the molecular speed curve forward and flattens it. This shift causes the fraction of molecules at low speeds to decrease and the fraction at high speeds to increase. Statement (C) claims the exact opposite effect, making it the incorrect conclusion. Statements A, B, and D are completely correct descriptions of ideal gas molecular behavior.
