A chemical reaction is a process in which a chemical substance is transformed into another chemical substance. A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae. It is a way to represent the chemical reaction in a concise and informative way.

Assertion (A) and Reason (R) in Chemistry:
Assertion (A): An equation is the shorthand representation of a chemical reaction.
Reason (R): A chemical reaction is a process in which a chemical substance is transformed into another chemical substance.
Explanation:
Chemical Equations:
- In chemistry, a chemical equation is a symbolic representation of a chemical reaction. It uses chemical symbols and formulas to describe the reactants and products involved in the reaction.
- Chemical equations are used to convey information about the substances involved, the ratio in which they react, and the products that are formed.
Chemical Reactions:
- A chemical reaction is a process in which one or more substances (reactants) undergo chemical changes to form new substances (products).
- During a chemical reaction, the atoms of the reactant molecules rearrange to form new chemical bonds, resulting in the formation of different substances.
- The reactants are written on the left side of the chemical equation, and the products are written on the right side.
Explanation of Assertion (A) and Reason (R):
- Assertion (A) states that an equation is the shorthand representation of a chemical reaction. This is true because a chemical equation represents the reactants and products involved in a chemical reaction using symbols and formulas.
- Reason (R) states that a chemical reaction is a process in which a chemical substance is transformed into another chemical substance. This is also true because during a chemical reaction, the reactant molecules undergo rearrangement of atoms to form new products.
Correct Answer:
- The correct answer is option 'B': Both A and R are true but R is NOT the correct explanation of A.
- Although both the assertion and reason are true, the reason does not provide a direct or specific explanation for the assertion.
- The reason states a general fact about chemical reactions, but it does not specifically explain why an equation is considered a shorthand representation of a chemical reaction.
- The assertion is true because a chemical equation does represent a chemical reaction, but the reason does not provide a direct explanation for this fact.
Conclusion:
- In summary, an equation is indeed a shorthand representation of a chemical reaction, and a chemical reaction involves the transformation of chemical substances. However, the reason does not provide a specific explanation for the assertion, making option 'B' the correct answer.
