Question

Which statement is the best explanation for the graph?

Answer 1

Answer:

The statement that correctly explains the graph attached is: "As temperature rises, gas particles are moving faster and may leave the solution."

We know that the solubility of a gas decreases with increasing temperature. This stems from the fact that the kinetic energy and velocity of gas molecules increases with increase in temperature.

That means that as a the temperature of a gas increases, its molecules move faster and are more likely to escape from solution rather than enter the solution.

This explains the decrease in the solubility of a gas with increase in temperature.
