5. Which of the following is the best explanation why a reaction in a closed container can appear to stop before all the reactants are converted to products? (2 points)
O
The forward reaction has run to completion, and the reverse reaction has started.
O
The reaction reaches equilibrium, and the forward and reverse reactions stop.
O
The forward and reverse reactions eventually reach the same rate.
The limiting reactant prevents the forward reaction from continuing to completion.

The forward and reverse reactions eventually reach the same rate.

Explanation:

The reactions which do not go on completion and in which the reactant forms product and the products goes back to the reactants simultaneously are known as equilibrium reactions.

Equilibrium state is the state when reactants and products are present but the concentrations does not change with time.

The equilibrium is dynamic in nature and the reactions are continuous in nature. Rate of forward reaction is equal to the rate of backward reaction and it appears as it has stopped.

did you find the answer?

the answer is b. dilution
