Which best describes a reaction in a state of equilibrium?
tamaranim1 [39]

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>
