Question
Chapter 4, Problem 4.15CP
Interpretation Introduction
Interpretation:
A method to calculate ΔH0R at different temperature from the given ΔH0f for thechemical compounds involved in the reaction needs to be depicted.
Concept Introduction:
Enthalpy change of a reaction is the amount of heat absorbed or evolved during the reaction which takes place at constant pressure conditions.
The standard enthalpy change for a reaction ΔH0R measured at 298 K and 1 atm is given in terms of the difference in the standard enthalpy of formation of the products and that of reactants.
i.e. ΔH0R = ∑npΔH0f(products) - ∑nrΔH0f(reactants) ------(1)
Here, np and nr are the number of moles of the products and reactants.
