A) 0.5 mol \[{{L}^{-1}}{{\min }^{-1}}\]
B) 0.005 mol \[{{L}^{-1}}{{\min }^{-1}}\]
C) 0.35 mol \[{{L}^{-1}}{{\min }^{-1}}\]
D) 0.850 mol \[{{L}^{-1}}{{\min }^{-1}}\]
E) None of the above
Correct Answer: B
Solution :
\[\Delta \,[A]={{[A]}_{final}}-{{[A]}_{initial}}=[0.150-0.200]\] \[=-\,0.050\,mol\,{{L}^{-1}}\] Average rate of reaction\[=-\frac{\Delta A}{dt}=-\frac{-\,[0.050]}{10}\] \[=0.0050\,\,mol\,{{L}^{-1}}\,{{\min }^{-1}}.\]
