Which statement is always true about a reversible chemical reaction?
o a. the concentration of reactants is higher than that of the products.
b. the products can form reactants, and the reactants can form products.
c. the concentrations of reactants and products are not constant.
d. the concentration of the products is higher than that of the reactants.

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)

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

since electrons are negative the answer is neagtaive
