If a chemical reaction can be brought about in more than one pathway, the net enthalpy change is the same provided that the initial and final states are the same. This statement is based on _____?
Everyday Science / Chemistry — Multiple-choice practice
اگر ایک کیمیائی رد عمل ایک سے زیادہ راستے میں لایا جا سکتا ہے، تو خالص انتھالپی تبدیلی ایک ہی ہے بشرطیکہ ابتدائی اور آخری حالتیں ایک جیسی ہوں۔ یہ بیان _____ پر مبنی ہے؟
- A. Law of Conservation of Mass
- B. Le Chatelier's Principle
- C. Hess's Law
- D. None of these
Correct answer
Hess's Law
Explanation
Explanation Hess's Law states that the total enthalpy change of a reaction is independent of the pathway, relying only on the initial and final states. This principle arises because enthalpy is a state function.
