Answer:
The equilibrium position will shift to the left, thus, favouring the backward reaction.
Explanation:
The equation for the reaction is given below:
3C(s) + 3H2(g) <==> CH4(g) + C2H2(g)
According to Le Chatelier's principle, if an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium will shift in order to neutralize the effect.
From Le Chatelier's principle, removing some C(s) implies removing some of the concentration of the reactants.
This will shift the equilibrium position to the left, thus, favouring the backward reaction (i.e forming more reactants) because removing C(s) implies that the products are now more than the reactants and as such, they will react to form more reactants.
