NEET Chemistry Enthalpy Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Exothermic Reaction | (i) ∆H is positive |
| (b) Endothermic Reaction | (ii) Heat absorbed by the system |
| (c) Enthalpy Change | (iii) ∆H is negative |
| (d) Standard Enthalpy | (iv) Depends on reaction conditions |
a-i, b-ii, c-iii, d-iv
a-iii, b-i, c-ii, d-iv
a-ii, b-iv, c-iii, d-i
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
Exothermic reactions have a negative enthalpy change (∆H is negative), while endothermic reactions have a positive enthalpy change (∆H is positive). The enthalpy change is the heat absorbed by the system at constant pressure, and standard enthalpy depends on the conditions under which a reaction is carried out.
