Answer : The correct option is, (B) The products can form reactants, and the reactants can form products.
Explanation :
Reversible reaction : It is a chemical reaction in which the reactants form products and products react together to give reactants back. That means reversible reaction can go in both direction forward as well as backward direction.
The general chemical reaction is:
aA + bB ⇄ cC + dD
(A and R are reactants and C and D are products)
When reversible reaction reaches to equilibrium point then at that point the concentration of reactant is equal to the concentration of product.
Hence, the correct option is, (B)
