The following data are available for carbon tetrachloride:

a. Compute the heat of vaporization of carbon tetrachloride at 200°C using only these data. 

b. Derive the following expression, which can be used to compute the heat of vaporization from the principle of corresponding states:

c. Compute the heat of vaporization of carbon tetrachloride at 200°C using the principle of corresponding states. 

d. Comment on the reasons for the difference between the heats of vaporization computed in parts (a) and (c) and suggest a way to correct the results to improve the agreement.
