The reaction will proceed in the forward direction if 2 moles of HI and 0.5 moles of both [tex]I_2[/tex] and [tex]H_2[/tex] are mixed in a separate 10 L vessel.
In chemistry, equilibrium is the condition existing when a chemical reaction and its reverse reaction occur at equal rates.
If K > Q, a reaction will proceed forward, converting reactants into products. If K < Q, the reaction will proceed in the reverse direction, converting products into reactants. If Q = K then the system is already at equilibrium.
In the first case K < Q, but in the second case K > Q, so the reaction will proceed forward in the forward direction.
