A) \[1.0\times {{10}^{-5}}\]
B) \[2.25\times {{10}^{-4}}\]
C) \[2.25\times {{10}^{-5}}\]
D) \[2.25\times {{10}^{-13}}\]
Correct Answer: C
Solution :
[c] \[{{\lambda }_{m}}=\frac{1000\kappa }{0.1}=\frac{1000\times 3.75\times {{10}^{-4}}}{0.1}=3.75;\] \[\alpha =\frac{{{\lambda }_{m}}}{\lambda _{m}^{\infty }}=\frac{3.75}{250}=1.5\times {{10}^{-2}}\]; \[{{K}_{a}}=C{{\alpha }^{2}}=0.1\times {{(1.5\times {{10}^{-2}})}^{2}}=2.25\times {{10}^{-5}}\]You need to login to perform this action.
