Vedclass · Answer

(D) The universal gas constant $R$ has different values depending on the units used for pressure and volume. $R = 8.314 \ J \ K^{-1} \ mol^{-1}$ ($SI$ units). Since $1 \ J = 10^7 \ erg$ and $1 \ J = 1 \ N \ m = 10^5 \ dyne 	imes 10^2 \ cm = 10^7 \ dyne \ cm$,options $A$,$B$,and $C$ are equivalent. Option $D$ $(8.31 \ atm \ K^{-1} \ mol^{-1})$ is incorrect because the unit of $R$ in $atm$ is $0.0821 \ L \ atm \ K^{-1} \ mol^{-1}$,not $8.31$.

In the equation $PV = nRT$,which one cannot be the numerical value of $R$?
