Question

A reaction mixture is at equilibrium. What happens when the amount of one of the reactants is lowered? aThe amount of the product increases. bThe rate of reverse reaction increases. cThe amount of the other reactant is also lowered. dThe equilibrium state is lost and cannot be restored.

Answer 1

Step-by-step explanation:

If the amount of one of the reactants is lowered, for example:

A + B <=> C + D, the equilibrium will shift to the left, to restore the lack of reactant and the rate of reverse reaction will increase.

Answer: b. The rate of reverse reaction increases.
