5. Construct the Cox chart for predicting the vapour pressure of ethanol and using the chart estimate the normal boiling point of ethanol and the vapour pressure at 323K. By how much \% these values depart from the actual values? The vapour pressure of ethanol at 293K and 363K are respectively, 5.76kPa and 157.03kPa. The vapour pressure of water is as follows: The experimental value of the normal boiling point is 351.7 and the vapour pressure at 323K is 29.2kPa
