A) \[k=8.7\times {{10}^{-3}}mo{{l}^{-1}}L{{s}^{-1}}\]
B) \[k=6.5\times {{10}^{-4}}mol{{L}^{-1}}{{s}^{-1}}\]
C) \[k=5.3\times {{10}^{-5}}{{s}^{-1}}\]
D) \[k=2.52\times {{10}^{-32}}mo{{l}^{-2}}{{L}^{2}}{{s}^{-1}}\]
Correct Answer: D
Solution :
: For third order reaction Rate constant \[K=\frac{dx}{dt}\times \frac{1}{{{[conc.]}^{3}}}\] \[=\frac{1}{Time}\times \frac{1}{{{[conc.]}^{2}}}\] \[=Tim{{e}^{-1}}mo{{l}^{-2}}{{L}^{2}}.\]
