Value of a=15.75095 atm L^2/ mol^2

Value of b=0.11986 L/mol

Explanation:

The formulas for constants a and b are given by:

For Constant a:

$a=\frac{27R^2T_c^2}{64P_c}$

Where:

T_c is critical Temperature

P_c is critical Pressure

R is gas constant=0.0820 atm.L/mol.K

$a=\frac{27*0.082^2*474.8^2}{64*40.6}\\ a=15.75095\ atm L^2/mol^2$

For Constant b:

$b=\frac{RT_c}{8P_c}$

Where:

T_c is critical Temperature

P_c is critical Pressure

R is gas constant

$b=\frac{0.082*474.8}{8*40.6}\\ b=0.11986\ L/mol$
