Which one of the following statements is NOT true about the effect of an increase in temperature on the distribution of molecular speeds in a gas?

Options

  1. AThe most probable speed increases
  2. BThe fraction of the molecules with the most probable speed increases
  3. CThe distribution becomes broader
  4. DThe area under the distribution curve remains the same as under the lower temperature

Correct answer

B. The fraction of the molecules with the most probable speed increases

Step-by-step solution

Most probable velocity increase and fraction of molecule possessing most probable velocity decreases
