NEET Chemistry Hess's Law Match the Following Question
Type: Match the Following-match the column-Medium-Class 11
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Hess's Law | (i) State function |
| (b) Enthalpy change | (ii) Independent of the reaction pathway |
| (c) Reaction reversed | (iii) Reversed in sign |
| (d) Extensive quantity | (iv) Depends on amount of substance |
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iv, b-iii, c-i, d-ii
D
a-iii, b-iv, c-ii, d-i
Correct Answer
Option A
Detailed Explanation
According to Hess's Law, enthalpy change is indeed independent of the reaction pathway (ii), it is a state function (i), reversing a reaction reverses the enthalpy change in sign (iii), and enthalpy is an extensive quantity (iv) depending on the amount of substance.
