A) \[\frac{2\text{R}}{4+12}\]
B) \[\frac{2\text{R}}{4-\text{R}}\]
C) \[\frac{4-\text{R}}{2\text{R}}\]
D) \[\frac{4+\text{R}}{2\text{R}}\]
Correct Answer: C
Solution :
\[{{n}_{T}}\,=\,(0.5+x)\] |
\[\text{PV}\,=n\,\times \,\text{R}\times \text{T}\] |
\[200\times 10\,=\,(0.5+x)\,\times \,\text{R}\,\times \,1000\] |
\[2\,=\,(0.5+x)\text{R}\] |
\[\frac{2}{\text{R}}\,=\,\frac{1}{2}+\,x\] |
\[\frac{\text{4}}{\text{R}}\,-\,1\,=\,2x\]\[\Rightarrow \] \[\frac{4-\text{R}}{2\text{R}}\,=\,x.\] |
