As per to Trouton's rule the entropy of vaporization of a liquid at its boiling point is 88 J/K mol. Explain what is the change in boiling point expected for a liquid with a boiling point of (a) 100 degrees C (b) 200 degrees C at 101,325 Pa in going to a reference state of 1 bar?
When HSCN is added, you expect that the equilibrium will shift to the right and the reaction mixture will become darker (more orange).
