Q. The normal boiling point of a compound (X) is 350 K (heat of vaporization, ∆vapH, = 30 kJ mol–1). The pressure required to boil ‘X’ at 300 K is ____Torr. (Round off to two decimal places)
(Ignore the temperature variation of ∆vapH; Gas constant R = 8.31 J mol–1 K–1 and 1 atm = 760 Torr)
Ans: 120.00 – 140.00
