MCQ
$S.I.$ unit of universal gas constant is
- A$cal/°C$
- B$J/mol$
- ✓$J\,mo{l^{ - 1}}\,{K^{ - 1}}$
- D$J/kg$
✓
Answer
Correct option: C.
$J\,mo{l^{ - 1}}\,{K^{ - 1}}$
c
From the relation $R =\frac{2 \Delta U }{3 nT }$
From the relation $R =\frac{2 \Delta U }{3 nT }$
where $\Delta U$ is the change in internal energy, $n$ is number of moles of gas and $\Delta T$ is change in temperature.
We get the $S.I.$ unit of universal gas constant is $JK ^{-1} mol ^{-1}$.
