Vedclass · Answer

(A) The universal gas constant $R$ has different values depending on the units used. For pressure in $atm$ and volume in $L$,$R = 0.0821 \ L \ atm \ K^{-1} \ mol^{-1}$. In $SI$ units,where pressure is in $Pa$ $(N/m^2)$ and volume is in $m^3$,$R = 8.314 \ J \ K^{-1} \ mol^{-1}$. Comparing the given options,option $A$ represents the correct value in $L \ atm \ K^{-1} \ mol^{-1}$.

The value of the universal gas constant $R$ is:
