Question

Which of the following is the best explanation why some reactions appear to stop before all the reactants are converted to products?

The reaction goes to completion.

The reaction reaches equilibrium and the products stop being formed.

The reversible reaction occurs at the same rate.

The limiting reactant prevents the forward reaction occurring.

Answer 1

I think its The reaction reaches equilibrium and the products stop being formed.

Answer 2

Option C is true.

Step-by-step explanation:

We are given that some reactions appear to stop before all the reactants are converted to products

We have to find the best explanation in given option why some reactions appear to stop before all the reactant are converted to products.

Reverse reaction : It is defined as the reaction in which reactants and products exist in a state of equilibrium.

Rate of froward reaction is equal to rate of backward reaction when the reaction is in equilibrium condition.

The reaction is not actually stop but it appear that the reaction to stop before all the reactants are concerted to products.

Hence, the reversible reaction occurs at the same rate occurs at the rate is best explanation for some reaction appear to stop before all the reactants are converted to products.

Option C is true.
