MCQ
The $SI$ unit of universal gas constant is
  • A
    $Watt\,{K^{ - 1}}mo{l^{ - 1}}$
  • B
    $Newton\,{K^{ - 1}}mo{l^{ - 1}}$
  • $Joule\,{K^{ - 1}}\,mo{l^{ - 1}}$
  • D
    $Erg\,{K^{ - 1}}\,mo{l^{ - 1}}$

Answer

Correct option: C.
$Joule\,{K^{ - 1}}\,mo{l^{ - 1}}$
c
(c) $PV = nRT \Rightarrow R = \frac{{PV}}{{nT}} = \frac{{Joule}}{{mole{\rm{ }} \times Kelvin}} = J{K^{ - 1}}mo{l^{ - 1}}$
