$\begin{aligned} & \mathrm{K}_{\mathrm{a}}=\frac{\mathrm{C} \alpha^2}{1-\alpha} \quad 1-\alpha \simeq 1 \ & \mathrm{~K}_{\mathrm{a}}=\mathrm{Co}^2 \ & \alpha=\sqrt{\frac{\mathrm{K}_{\mathrm{a}}}{\mathrm{C}}} \ & \% \alpha=\sqrt{\frac{\mathrm{K}_{\mathrm{a}}}{\mathrm{C}}} 	imes 100=\sqrt{\frac{1.34 	imes 00^{-6}}{0.01}} 	imes 100 \ & =1.15 \% \ & \end{aligned}$
