a' and 'b' are van der waals constant for gases. Chlorine is more easily liquefied than ethane because-

A

a and b for `Cl_(2) lt a and b ` for `C_(2)H_(6)`

B

a for `Cl_(2) lt a ` for `C_(2)H_(6)` but b for `Cl_(2) gt b` for `C_(2)H_(6)`

C

a for `Cl_(2) gt a` for `C_(2)H_(6)` but b for `Cl_(2) ltb` for `C_(2)H_(6)`

D

a and b for `Cl_(2) gt a and b` for `C_(2)H_(6)`

Text Solution

Verified by Experts

The correct Answer is:
C
van der waals constant 'a' is a measure of intermolecular forces of attraction of a gas whereas 'b' is measure of the size of gas molecules. Hence, more is the value of 'a' more easily that gas will be liquiefied.

For a real gas, the van der Waals constant 'a' is zero. Can the gas the liquefied? Explain.

For real gases van der Waals’ equation is written as (p+(an^2)/V^2)(V-nb)=nRT where, 'a' and 'b' are van der Waals' constants Two sets of gases are O_2CO_2.H_2 and He CH_4O_2 and H_2 The gases given in set I in increasing order of 'b' and gases given in set II in decreasing order of ‘a’, are arranged below. Select the correct order from the following.

In the van der waals equation, 'a' signifies-

Set-I: O_(2),CO_(2),H_(2) and He, Set-II: CH_(4),O_(2) and H_(2) . The gases in set-I in increasing order of 'b' and gases given in set-II in decreasing order of 'a', are arranged below, where 'a' and 'b' are van der waals constants. Selection the correct order from the following-
