Question

1. The vapor pressure, P of a certain liquid was measured at two temperatures, T. from this data:


T(K) and P(kpa)
275 3.57
825 6.57

for the enthalpy how would this be plotted on the graph

point 1:
point 2:

2. What is the rise, run, and slope


3. What is the enthalpy of vaporation of this liquid (in j/mol)?
