consists only of a forward reaction
consists only of a reverse reaction
consists of both a forward and a reverse reaction
consists of neither a forward nor a reverse reaction
none of the above
question 2 (1 point)
a system has reached chemical equilibrium. which is true of

Explanation:

A reversible reaction is defined as a reaction that can proceed in both the forward and reverse directions. So, it does not consist only of a forward reaction (as the first option suggests), nor only of a reverse reaction (as the second option suggests), and it is not the case that there are no forward or reverse reactions (as the fourth option suggests). The third option correctly states that it consists of both a forward and a reverse reaction.

Answer:

consists of both a forward and a reverse reaction
