The best statement
which describes a reaction in a state of equilibrium is letter D. <span>The rate of the forward
reaction equals the rate of the reverse reaction and the </span>concentrations of products and
reactants are constant.
>Chemical equilibrium<span> is defined as<span> the state in which both reactants and products are present
in </span></span>concentrations<span> which have no further tendency to change with time. This state results when the forward
reaction proceeds at the same rate as the </span>reverse
reaction<span>. The </span>reaction rates<span> of the forward and backward reactions are generally not zero,
but equal. Thus, there are no net changes in the concentrations of the reactant(s)
and product(s).</span>
