# A relation to Le-chatelier's principle?

## Homework Statement

##Fe+2HCl(g) \longrightarrow FeCl_2+H_2##. In my textbook it's written that liberation of ##H_2## prevents formation of ##FeCl_3##.
But why?And how?

## The Attempt at a Solution

I think it is related to the Le-Chatelier principle . As ##H_2## is liberated more, the reaction equilibrium is shifted towards the products . So more ##FeCl_2## will be produced. But for ##FeCl_3##, I think there should be an alternative path for the reactants to produce ##FeCl_3## along with the path producing ##FeCl_2## and ##H_2##. I think this path is neglected when the reaction equilibrium is shifted towards the products of the other path.Am I correct , or is there any other reason for that?
