The Boltzmann distribution for one mole of a gas at temperature T is shown. [Figure 15.1] One mole of the same gas is added, and the gas remains at temperature T. Which dotted curve shows the distribution with the added gas? [Figure 15.2]
✓ Correct Answer
The correct answer is A: Diagram showing a Boltzmann distribution with a higher peak and the same overall shape as the original solid curve.
