At `440^(@)C`, the equilibrium constant (K) for the following reaction is `49.5, H_(2)(g)+I_(2)(g) hArr 2HI(g)`. If `0.2` mol of `H_(2)` and `0.2` mol of `I_(2)` are placed in a `10-L` vessel and permitted to react at this temperature, what will be the concentration of each substance at equilibrium?
