Answer :
Answer:
A. Reversible Process
Explanation:
Going through the meaning of the options we have;
A Reversible: This reaction involves a backward and forward step.. This means that reactant would react to form products and products in turn wold react to form reactants. This is the correct option.
B. Elementary process: This refers to a single step reaction with a single transition state and no intermediates. This option is wrong because that is not what the question says.
C. Equilibrium Reaction: This refers to a reaction in which there is no change in the concentration of the reactants and products. Rate of forward reaction is equal to the rate of backward reaction.
D. Forbidden Reaction: This is not the correct option.
E. Forward process: This refers to the reaction that involves reactants reacting to form products. This is also not correct as the question states that the products are also able to form reactants.
