Correct Answer: C
Solution :
From experimental values of and b, sequence of van der Waals? constant, (b) isGas | \[{{H}_{2}}\] | \[He\] | \[{{O}_{2}}\] | \[C{{O}_{2}}\] |
Value of b | \[0.0273\] | \[0.0318\] | \[0.0273\] | \[0.0427\] |
Gas | \[C{{H}_{4}}\] | \[{{O}_{2}}\] | \[{{H}_{2}}\] |
Value of b | \[2.25\] | \[1.36\] | \[0.244\] |
