Anegative change in free energy, or −δg, represents a spontaneous reaction.

true

false

The answer to your question is: True

Explanation:

Gibbs energy is the energy related to a chemical reaction that can be used to do some work.

Gibbs energy is calculated from a reaction and also the spontaneity can be determined.

In a spontaneous reaction Gibbs energy is always negative.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
