Understanding Vapor Pressure and Solutes

What happens to the vapor pressure of a solvent when a non-volatile solute is dissolved in it?

• The vapor pressure increases.

• The vapor pressure decreases.

• The vapor pressure remains the same.

• The vapor pressure becomes zero.

What is the main factor that affects the tonoscopic effect?

• The type of solute.

• The amount of solute particles.

• The color of the solute.

• The temperature of the solvent.

If you dissolve more solute in a solvent, what happens to the vapor pressure?

• It increases.

• It decreases.

• It stays the same.

• It doubles.

What happens to the boiling point of a solvent when a solute is added?

• It decreases.

• It increases.

• It stays the same.

• It becomes zero.

Does the tonoscopic effect depend on the identity of the solute?

• Yes, it depends on the type of solute.

• No, it depends on the number of solute particles.

• Yes, it depends on the color of the solute.

• No, it depends on the temperature of the solvent.

What is required for a solvent to reach its boiling point after a solute is added?

• Less heat.

• More heat.

• No heat.

• The same amount of heat.

What is the effect of adding a non-volatile solute on the solvent's vapor pressure?

• It makes the vapor pressure higher.

• It makes the vapor pressure lower.

• It has no effect on vapor pressure.

• It makes the vapor pressure equal to atmospheric pressure.

If two different solutes have the same number of moles, what can be said about their effect on vapor pressure?

• They have different effects.

• They have the same effect.

• One has no effect, the other does.

• It depends on the color of the solute.

What happens to the boiling point of a solvent when the vapor pressure is decreased?

• The boiling point decreases.

• The boiling point increases.

• The boiling point stays the same.

• The boiling point becomes zero.

What is the relationship between solute concentration and vapor pressure reduction?

• Directly proportional.

• Inversely proportional.

• No relationship.

• Exponentially proportional.
