Question

Under conditions of high temperature, the attraction forces between molecules of real gas become insignificant. At a certain pressure under these conditions, the molar volume was found to be 10 times the van der Waals coefficient ' b '. The molar volume of an ideal gas under these conditions when expressed in terms of ' b ' is " Xb ". What is the value of 2X

TestHub · Accepted Answer

V m ​ = 10 b ⇒ b = 10 V m ​ ​ So, PV m ​ ( 10 9 ​ ) = RT ⇒ RT PV m ​ ​ = 9 10 ​ ∴ Z = V i ​ V R ​ ​ = 9 10 ​ ⇒ V i ​ = 10 9 V R ​ ​ ⇒ V i ​ = 9 b
