describe what the heating curve of ethanol shows about the rate of temperature increase and the enthalpy of vaporization.\na the temperature increase converts bonding forces into intermolecular forces.\nb the faster the rate temperature increase then the faster the enthalpy occurs.\nc the enthalpy of vaporization is unaffected by the rate of temperature increase.\nd the rate for both the temperature increase and the enthalpy change are the same.

Answer

Brief Explanations:

  • Enthalpy of vaporization is a characteristic property of a substance. It represents the amount of energy required to convert a liquid into a gas at its boiling point.
  • The rate of temperature increase during heating (which is related to the slope of the non - plateau regions of the heating curve) does not affect the enthalpy of vaporization value. The enthalpy of vaporization is determined by the nature of the intermolecular forces in the liquid and is a fixed value for a given pure substance at a constant pressure.

Answer:

C. The enthalpy of vaporization is unaffected by the rate of temperature increase.
