Question

Click on the Run button in the activity. Watch how the solubility of a gas changes as pressure is increased and then decreased during the run. Which of the following statements correctly explain the relationship between the solubility of a gas and its pressure?

Check all that apply.

a) The solubility of nitrogen gas at 2.00 atm is twice the solubility of the gas at 1.00 atm.

b) As pressure is increased, the rate at which gas molecules enter the solution decreases.

c) The solubility of a gas decreases with a decrease in pressure.

d) Fewer gas molecules are soluble at higher pressures.

e) More gas molecules are soluble as pressure is increased.

f) The concentration of gas particles in the solution is higher at 4.25 atm than at 1.00 atm.

g) As pressure decreases, the concentration of gas molecules in the solution increases.
