It is expected that the data listed below between the vapour pressure p of water (in kPa) at different temperatures T (in K) will follow the relationship:
where A and B are two constants which can be determined via curve fitting.
Estimate A and B based on the first two entries of the data below and calculate the error of using these values as a curve-fit for all the data.

In this lab, you will determine the vapour pressure of ethanol (P) at various temperatures and use this data to find the enthalpy of vaporization (ΔvapH). If a plot of ln P vs. 1/T gives a slope of -9782 K, what is the ΔvapH in kJ/mol? Do not worry about how realistic the value is. Assume R = 8.314 J mol-1 K-1.

PAKI T UIJJ 5.9 Plot the vapour pressure data for a mixture of benzene (B) and acetic acid (A) given below and plot the vapour pressure/composition curve for the mixture at 50°C. Then confirm that Raoult's and Henry's laws are obeyed in the appropriate regions. Deduce the activities and activity coefficients of the components on the Raoult's law basis and then, taking B as the solute, its activity and activity coefficient on a Henry's law basis. Finally, evaluate the excess...

Exercise 6. Estimate the K-values and a of a vapour-liquid mixture of water (W) and methane (M) at P = 2 atm, T = 20 and 80°C. What is the effect of T on the component distribution? At these conditions, water exists mainly in the liquid phase and will follow Raoult's law. Because methane has a critical temperature of -82.5 °C, well below the temperatures of interest, it will exist mainly in the and follow Henry's law. Table 1: From...
