Answer and Explanation:

It is worthy to be mentioned that the equilibrium in this reaction is dynamic equilibrium.

In terms of concentration: the concentration of reactants (CH4) and products (C2H2 & H2) do not change and be constant at the equilibrium, that 2 moles of CH4 give one mole of C2H2 and 3 moles of H2. In terms of reactions that occur: the reactions that occur at the equilibrium are the forward and the reverse reaction. The forward reaction: 2CH4 → C2H2 + 3H2 and the reverse reaction: C2H2 + 3H2 → 2CH4. In terms of reaction rates: At equilibrium the rate of the forward reaction is equal to the rate of the reverse reaction.
