In which of the following reaction can equilibrium be attained?
In which of the following reaction can equilibrium be attained?
The correct option is A (a) Reversible reaction
Explanation for Correct answers
Equilibrium can be attained in (a) reversible reaction.
Explanation
- A reversible reaction is defined as a chemical reaction where the reactants and the products react together to give the product, which can further be reacted back to form reactant.
- Representation of reversible reaction:
- The state in which the transformation of reactants into products and the conversion of products back into reactants occur simultaneously at the same rate and state of balance is known as equilibrium.
- When there is no further change in the concentrations of the reactants and the products due to the equal rates of the forward and reverse reactions, the system is said to be in a state of dynamic equilibrium.
- The reversible reaction can proceed in both forward and reverse directions hence, in this type of reaction equilibrium can be attained.
The correct answer is option (a).
Explanation for incorrect answers
(b) Irreversible reaction is a reaction in which the reaction either goes forward or backward for completion.
The irreversible representative is represented as:
Hence, option b is incorrect.
(c ) Redox reaction: in this reaction both oxidation and reduction takes place simultaneously. It may or may not be in equilibrium. Hence, option c is incorrect.
(d) Single displacement reaction: In this reaction higher active elements displaced the less active elements, it does not attains equilibrium hence, option d is incorrect.
