The Antoine equation for the vapor pressure of a liquid at a given temperature is given by

Fantastic news! We've Found the answer you've been seeking!

Question:

p* = eA−B / (T + C)

The constants for benzene are

A = 15.9008

B = 2788.51°C

C = 220.80°C

for the vapor pressure in millimeters of mercury (mmHg). Linearize the equation about a temperature of 40°C.

Compare the actual vapor pressure (from the Antoine equation) at 45 and 60°C with the vapor pressure calculated from the linearized equation. What is the percent difference in each case? Comment on the suitability of the linearized equation.
