Question
Chapter 5, Problem 49QP
Interpretation Introduction
Interpretation:
The enthalpy of formation of methanol is to be calculatedwith the help of given heat of combustion.
Concept introduction:
Hess’s Law states that the change in enthalpy fora
The enthalpy change for the reaction is a state function. It depends upon the initial and final states of the system and not on the path followed.
If any reaction is reversed, then the sign of enthalpy change will also reverse. If enthalpy change is positive, then it will become negative and vice versa.
If any reaction is multiplied or divided any number, then its enthalpy change is also multiplied and divided by the same number.
