Consider the following equilibrium: #2H_2(g) + X_2(g) rightleftharpoons 2H_2X(g) + Delta#. What will an addition of #X_2# to this system cause to happen?

An increase in the amount of #2"H"_2"X"# formed at equilibrium compared to before.

Explanation:

By adding more #"X"_2#, you are adding more reactants, shifting the equilibrium to the right, as there are now reactants than products,and equilibrium has not been reached, mor #2"H"_2# will react with the excess #"X"_2# to decrease the amount of reactants and increase the amount of products until equilibrouk is reached.
