Solution

The correct option is D $0.0821 J K^{- 1} m o l^{- 1}$
The value of ideal gas constant in vaious units can be given as follow:
$R = 8.314 P a m^{3} K^{- 1} m o l^{- 1}$
$R = 8.314 \times 10^{- 2} b a r L K^{- 1} m o l^{- 1}$
$R = 8.314 J K^{- 1} m o l^{- 1}$
$R = 0.0821 L a t m K^{- 1} m o l^{- 1}$ .
Thus value given in option C is incorrect.
