) for the given chemical reaction, is given by the equation:![K_{c} = \frac {[HI]^{2}}{[H_{2}]\: [I_{2}]}](/tpl/images/0435/6174/f8601.png)
![K_{c} = \frac {[HI]^{2}}{(0.95\: M) \times (0.019\: M)}](/tpl/images/0435/6174/d2511.png)
![\Rightarrow K_{c} = 713.59 = \frac {[HI]^{2}}{0.01805}](/tpl/images/0435/6174/fef3c.png)
![\Rightarrow [HI]^{2} = 713.59 \times 0.01805 = 12.88](/tpl/images/0435/6174/d4ab1.png)
![\Rightarrow [HI] = \sqrt {12.88} = 3.589 M](/tpl/images/0435/6174/5120a.png)
