Consider the following chemical reaction:2CH4(g) C2H2(g) + 3H2(g)Describe what is happening within the system when it is at equilibrium in terms of concentrations, reactions that occur, and reaction rates.

Answer:

The system is in dynamic equilibrium: CH4 is decomposing into C2H2 and H2 while C2H2 and H2 react to form CH4. Both reactions continue at equal rates, so the concentrations of all substances remain constant.
