NEET Physics (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Standard Enthalpy of Formation | (i) Formation from elements in their stable states |
| (b) Reference State of Carbon | (ii) C graphite |
| (c) Standard Enthalpy of Reaction | (iii) Heat change per mole of reaction |
| (d) Reference State of Water | (iv) H2O liquid |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-iv, b-iii, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
The correct match shows the definition of standard enthalpy of formation as the heat change when one mole of a compound is formed from its elements in their stable states. The reference state of carbon is graphite, and water's reference state is liquid at standard conditions.
