Q. For $H_{2} O$

$T_{C} = 647 K$

$P_{C} = 218$ atm

$V_{C} = 0.057 L m o l^{- 1}$

What is the value of 'a' for $H_{2} O ?$

$2.12 L^{2} a t m m o l^{- 2}$

$0.019 L^{2} a t m m o l^{- 2}$

$8.31 L^{2} a t m m o l^{- 2}$

$0.082 L^{2} a t m m o l^{- 2}$

$a = 3 p_{C} V_{C}^{2}$

$= 3 \times 218 \times (0.057)^{2}$

$= 2.12 L^{2} a t m m o l^{- 2}$
