Pressure of a gas at 127^oC is 10 mm Hg and the pressure at 527^oC is 20 Pa, what is the value of B?
(a) 225.1
(b) 365.5
(c) 499.2
(d) 554.5
This question was posed to me during an online interview.
This is a very interesting question from Modeling and Predicting Vapor Pressure in section Real Gases: Equations of State, Single Component Two Phase Systems, Saturation & Condensation of Basic Chemical Engineering
