Assertion(A): Decomposition reactions are generally exothermic. Reason(R): In decomposition reactions, single reactant breaks down into two or more
products.
i) Both A and R are true and R is correct explanation of the assertion.
ii) Both A and R true but R is not the correct explanation of the assertion.
iii) A is true but R is false.
iv) A is false but R is true
Answers
Answer:
iv) A is false but R) is true
Answer: The correct option is (i) Both A and R are true and R is the correct explanation of the assertion.
Decomposition reactions are generally exothermic because they involve the breaking down of a single reactant into two or more products. This release of energy occurs because the bonds holding the reactant molecule together are broken, which releases energy in the form of heat.
The reason given in the assertion is correct. Decomposition reactions result in the formation of two or more products, which requires energy to break the bonds holding the reactant molecule together. The energy released when these bonds are broken is greater than the energy required to break them, resulting in a net release of energy in the form of heat. Therefore, the statement made in the reason is the correct explanation of the assertion.
