A) 560 mm Hg
B) 680 mm Hg
C) 920 mm Hg
D) 600 mm Hg
Correct Answer: C
Solution :
For first order reaction |
\[\underset{640-2x}{\mathop{2A(g)}}\,\,\xrightarrow{\,}\,\underset{3x}{\mathop{3B\,(g)}}\,\] |
\[\therefore \] \[{{p}_{Total}}=640+x\] |
\[k=\frac{2.303}{t}\,\log \,\frac{a}{a-x}\] |
\[\frac{0.693}{{{t}_{1/2}}}=\frac{2.303}{36}\log \,\frac{640}{640-2x}\] |
\[\frac{2.303\,\log \,2}{12}=\frac{2.303}{36}\,\log \,\frac{640}{640-2x}\] |
\[\log {{2}^{2}}=\log \,\frac{640}{640-2x}\] |
\[x=280\] |
\[\therefore \] \[{{p}_{Total}}\,=640+280\,=920\,mm\] |
