Q. According to Hess's law, the enthalpy change of a reaction:

हेस के नियम के अनुसार, किसी प्रतिक्रिया का एन्थैल्पी परिवर्तन:

A
Depends on the path taken between reactants and products
अभिकारकों और उत्पादों के बीच अपनाए गए पथ पर निर्भर करता है
B
Is independent of the path taken between reactants and products
अभिकारकों और उत्पादों के बीच अपनाए गए पथ से स्वतंत्र है
C
Is always exothermic
सदैव ऊष्माक्षेपी होता है
D
Is always endothermic
सदैव ऊष्माशोषी होता है

Explanation

Hess's Law states that the total enthalpy change of a chemical reaction is the same regardless of the path taken from reactants to products. It depends only on the initial and final states (i.e., a state function).
