Answer: H2O
Explanation: The given balanced chemical reaction is,
This reaction is a reversible reaction.
The rate of forward reaction will be,
The rate of backward reaction will be,
And at equilibrium the rate of reaction is equal to the rate of backward reaction divided by the rate of forward reaction.
