Question

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?

Answer 1

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.
