What Is Chemical Equilibrium?a. When all reactants turn into products, the chemical reaction reaches equilibrium. c. Reactants and products will have the same concentration at equilibrium. d. At equilibrium, the forward reaction and reverse reaction will have the same reaction rate. e. A chemical reaction stops when it reaches equilibrium.

The correct answer is d. At equilibrium, the forward reaction and reverse reaction will have the same reaction rate.

Explanation:

When a reaction begins, the reactants combine to form products. At the same time of product formation, the convertion of products into reactants also occur. The reaction reaches chemical equilibrium when the rate of forward reaction (the convertion of reactant into products) is equal to the rate of reverse reaction (the convertion of product into reactants). Upon this state, the concentration of reactants and products do not change in time (that does not mean that the concentration of reactants and products are equal, but that once the chemical equilibrium is reached, their concentrations at this point will not vary with the time because the forward and reverse reactions are occuring at the same velocity).

they are both synthetic elements
