Question

Consider the following statements: If the van der Waal’s parameters of two gases are given as

a (atm lit2mol–2) b (lit mol–1)

Gas X: 6.5 0.056

Gas Y: 8.0 0.011

then (i) : VC (X) < VC (Y) (ii) : PC (X) < PC (Y)

(iii) : TC (X) < TC(Y)

Select correct alternate:

• A. (i) alone
• B. (i) and (ii)
• C. (i), (ii) and (iii)
• D. (ii) and (iii)

Answer 1

Answer: (D)

(ii) and (iii)

Answer 2

$\mathrm { T } _ { \mathrm { C } } \propto \frac { \mathrm { a } } { \mathrm { b } }$
