The graph (below) shows the distribution of molecular velocities. How many of the statements are true?

- At a given temperature, curve A represents gas particles with the smallest molar mass
- For a given gas sample, curve D represents the highest temperature
- At a given temperature, curve D represents gas particles with the highest molar mass
- For a given gas sample, the broader the velocity distribution, the lower the temperature

- 0 b) 1 c) 2 d) 3 e) 4

We’re being asked **how many statements are true** involving the distribution of **molecular velocities**.

In the graph, the y-axis is the **relative number of particles** while the x-axis is the **molecular speed**. We can think of the molar mass of a gas as being related to the number of particles (↑ molar mass = ↑ particles).
