A) \[0.182\times {{10}^{-5}}\]
B) \[1.79\times {{10}^{-5}}\]
C) \[0.8\times {{10}^{-5}}\]
D) None of these
Correct Answer: B
Solution :
As \[{{K}_{a}}=C{{\alpha }^{2}}.\] As, \[C=0.1\,M,\,\alpha =1.34%=0.0134.\] So,\[K\alpha =0.1\times {{(1.34\times {{10}^{-2}})}^{2}}\] \[=1.79\times {{10}^{-5}}\] Hence, the correct option is (b).
