Question
Chapter 5, Problem 87AP
Interpretation Introduction
Interpretation:
The enthalpy change of the reaction is to be calculated.
Concept introduction:
The change in the enthalpy of a reaction, when the reactants are converted to products, is the same, regardless of whether the reaction takes place in one step or in many steps. This law is known as Hess’s law.
On adding the thermochemical equations, the enthalpy change value is also added, which gives the enthalpy change of the net reaction.
On reversing any equations, the sign of the enthalpy change value is changed to the opposite sign.
