What is enthalpy of fusion?

What is enthalpy of the fusion?

6.24 g of ethanol are vapourized by supplying 5.89 kj of heat energy. What is enthalpy of vapourization of ethanol?

What is the enthalpy of atomization? Give an example.

Answer the following questions : What is latent heat of fusion ? State its unit .

For KCl, Delta_LH = 699 kJ//mol^-I and Delta_(hyd)H = -681.8 kJ//mol^-1 . What will be its enthalpy of solution?

What is standard enthalpy of combustion? Give an example

For melting of ice at 25^@C the enthalpy of fusion is 6.97 kj mol^(-1) and entropy of fusion is 25.4 JK-1 mol^(-1) . Calculate free energy change and predict whether melting of ice is spontaneous or not at this temperature.

What is phase transition? Define : Enthalpy of fusion

Write thermochemical equation for complete oxidation of one mole of H_2(g) . Standard enthalpy change of the reaction is -286 kJ. Is the value -286 kJ, enthalpy of formation or enthalpy of combustion or both? Explain.

Why is latent heat of vaporisation much larger than latent heat of fusion?
