Question
Chapter 9, Problem 13QAP
Interpretation Introduction
Interpretation:
The vapor pressure of octane is obtained by the following data-
Vp(mmHg) | 10 | 40 | 100 | 400 |
t (°C) | 19.2 | 45.1 | 65.7 | 104.0 |
The graph between ln(vp) and 1/T is to be plotted. The heat of vaporization of octane is to be estimated by this graph.
Concept introduction:
The relation between pressure, temperature and change in enthalpy of vaporization is as follows:
Here,
P = pressure
T = temperature
A = y-intercept from the graph.
