Question

In a reverse reaction, products are formed from reactants and reactants are formed from products. When they yield the same amount, it is called:

A. the law of mass action
B. activation energy is released
C. chemical equilibrium is reached
D. None of the above

Answer 1

In a reverse reaction, when the forward and reverse reactions occur at the same rate, the reaction reaches chemical equilibrium.

Step-by-step explanation:

The correct answer is C. chemical equilibrium is reached. In a reverse reaction, products are formed from reactants and reactants are formed from products. When the forward and reverse reactions occur at the same rate, the reaction is said to be at equilibrium. At equilibrium, the concentrations of the reactants and products are constant, but it does not mean that the concentrations are equal. The law of mass action is a related concept that describes the relationship between the amounts of reactants and products at equilibrium.
