![Kc=\frac{[AsH_3]^2}{[As]^2[H_2] ^3}=1.27](/tpl/images/0545/3503/09ec8.png)
![Kc=\frac{[As][H_2] ^{3/2}}{[AsH_3]}](/tpl/images/0545/3503/b2ae8.png)
![\sqrt{Kc} =\sqrt{\frac{[AsH_3]^2}{[As]^2[H_2] ^3}} =\sqrt{1.27}](/tpl/images/0545/3503/dc32b.png)
![\frac{\sqrt{[AsH_3]^2} }{\sqrt{[As]^2} \sqrt{[H_2] ^3} } =\sqrt{1.27}](/tpl/images/0545/3503/19f81.png)
![\sqrt{1.27}=\frac{[AsH_3]}{[As][H_2] ^{3/2}}](/tpl/images/0545/3503/e4fe4.png)
![Kc'=\frac{1}{\sqrt{1.27} }=\frac{[As][H_2] ^{3/2}}{[AsH_3]}=0.887](/tpl/images/0545/3503/a88a2.png)
