At equilibrium, . At equilibrium, . all chemical reactions have ceased the rate constants of the forward and reverse reactions are equal the rates of the forward and reverse reactions are equal the value of the equilibrium constant is 1

At equilibrium, the rate of the forward, and the reverse reactions are equal.

Explanation:

In an equilibrium chemical reaction, the rate of forward reaction, is equal to the rate of reverse reaction. Note that the reactions does not cease at equilibrium, but rather, the reactants are converted to product, at the same rate at which the product is also being converted into the reactants in the reaction. When chemical equilibrium is reached, a careful calculation of the value of equilibrium constant is approximately equal to 1.

NB: If the value of equilibrium constant is far far greater than 1, then the reaction will favors more of the forward reaction, and if far far less than 1, the reaction will favor more of the reverse reaction.

the answer is a! (2.9 x 10^-18 j) hope i could someone. : )
