Question

Check my answer!?

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

A. The reaction goes to completion.

B. The reaction reaches equilibrium and the products stop being formed.

C. The reversible reaction occurs at the same rate.

D. The limiting reactant prevents the forward reaction occurring.

I believe it's B or C, i want to go with C?

Answer 1

The reaction reaches the equilibrium, but that doesn't mean that products stop being formed (so B is false)
In a chemical equilibrium, the reverse reaction is converting products into reactants as fast as products are formed in the forward reaction. So both the forward and reverse reactions taking place equally fast.
You should go with C :)

Thank you!!(:
