Respuesta :
Here ΔH°vap for die ethyle ether = 27.3 KJ/mol
The enthalpy change when 1.75moles of die ethyle ether charges from the liquid to the gas phase will be,
ΔH = (27.3 × 1.75)KJ
ΔH= 47.775 KJ
What is enthalpy?
Enthalpy is an energy-like attribute or state function; it has the dimensions of energy (and so is measured in joules or ergs), and its value is controlled wholly by the system's temperature, pressure, and composition, rather than its history.
What is enthalpy with example?
This Enthalpy is equal to the sum of the internal energy of such a system with the constant. You must realise that the forms of energy fluctuate, while Enthalpy remains constant. For example, when water freezes into ice, some energy is used in the process, which is referred to as Enthalpy.
Hence47.775 KJ is a correct answer.
