Q. In the equation of state of an ideal gas $pV = nRT,$ the value of the universal gas constant would depend only on
A) The nature of the gas
B) The pressure of the gas
C) The units of the measurement
D) None of the above
Explanation
(c)
In ideal gas equation the value of universal gas constant depends on the units of the measurement.
Numerical values of $R,$
$(a)\ 0.0821\ L\ atm\ K^{- 1}\ {mol}^{- 1}\$
$(b)\ 8.314\ J\ K^{- 1}\ {mol}^{- 1}$
$(c)\ 8.314\ \times 10^{7}\ erg\ K^{- 1}\ {mol}^{- 1}$
