**Prelaboratory Assignment: Vapor Pressure of Water**1. The data below are for the vapor pressure of toluene:| v.p. (mm Hg) | 40 | 60 | 80 | 100 ||--------------|----|----|----|-----|| T (°C) | 32 | 40 | 47 | 52 |Using this data, plot ln P versus 1/T.a) What is the slope of the line?b) What is the heat of vaporization of toluene?c) From the graph, estimate the normal boiling point of toluene. How did you choose this point?d) From the graph, estimate the freezing point of toluene. How did you choose this point? (Note: The graph referred to in this assignment involves plotting the natural logarithm of the vapor pressure (ln P) against the reciprocal of the temperature in Kelvin (1/T). The slope of this line can be used to calculate the heat of vaporization. The boiling and freezing points can be estimated from where specific points intersect on the graph based on known physical properties.)

We can plot ln(P, mmHg) Versus 1T(K) by taking ln(P, mmHg) in Y-axis and 1T(K) in X-axis.
