<u>Answer:</u> The change in enthalpy for the given system is -642.8 kJ/mol
<u>Explanation:</u>
To calculate the change in enthalpy for given Gibbs free energy, we use the equation:
where,
= Gibbs free energy = -717.5 kJ/mol = -717500 J/mol (Conversion factor: 1 kJ = 1000 J)
= change in enthalpy = ?
T = temperature = 337 K
= change in entropy = 221.7 J/mol.K
Putting values in above equation, we get:
Hence, the change in enthalpy for the given system is -642.8 kJ/mol
Answer:
The correct option is;
a. The particles will gain a large amount of kinetic energy
Explanation:
As the water temperature reaches 100°C, which is the boiling point for water at atmospheric pressure, the continued heating is then used to break up the strong inter molecular forces between molecules of the water such that the individual molecules are free to move about and due to the high temperature, have gained considerable amount of kinetic energy for the to rise to appreciable height and to also spread.
The heat which converts water into steam is called latent heat as during the boiling phase, the temperature of the water remains constant.
Answer:
Is there any other part to this question? If not I'm pretty sure the answer is 205.5 kJ
