MediumAt $783 \, K$ in the reaction,$H_{2(g)} + I_{2(g)} \rightleftharpoons 2 HI_{(g)}$,the molar concentrations $(mol \, L^{-1})$ of $H_2, I_2$ and $HI$ at some instant of time are $0.1, 0.2$ and $0.4$,respectively. If the equilibrium constant is $46$ at the same temperature,then as the reaction proceeds:
- Athe amount of $HI$ will increase
- Bthe amount of $HI$ will decrease
- Cthe amount of $H_2$ and $I_2$ will increase
- Dthe amount of $H_2$ and $I_2$ will not change
