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 $$323\mathrm{K}$$. By how much \% these values depart from the actual values? The vapour pressure of ethanol at $$293\mathrm{K}$$ and $$363\mathrm{K}$$ are respectively, $$5.76\mathrm{kPa}$$ and $$157.03\mathrm{kPa}$$. The vapour pressure of water is as follows: The experimental value of the normal boiling point is $$351.7$$ and the vapour pressure at $$323\mathrm{K}$$ is $$29.2\mathrm{kPa}$$.
