Question

Which of the following is Greater?

(a) Boyle’s temperature

(b) Boyle’s temperature = critical temperature

(c) Critical temperature

(d) Boyle’s temperature = 1/critical temperature

I got this question by my school teacher while I was bunking the class.

The above asked question is from States of Matter topic in portion States of Matter of Chemistry – Class 11

Answer 1

Right answer is (a) Boyle’s temperature

To explain I would say: Boyle’s temperature TB is given by a/Rb critical temperature TC is given by 8a/27Rb, where a is the pressure correction term and b is a volume correction term as per van der Waal’s equation. So Boyle’s temperature is greater than the critical temperature.
