Chapter 6, Problem 35QRT

Interpretation Introduction

Interpretation:

The ${\Delta }_r{H}^o$ formation of carbon monoxide to carbon dioxide by combination of molecular oxygen and this reaction exothermic or endothermic have to be estimated.

Concept Introduction:

According to Hess’s Law to estimate ${\Delta }_r{H}^o$ by breaking all the bonds in the reactants and then we will form all the bonds the opposite of breaking in the products.

  ${\Delta }_r{H}^o={\displaystyle \sum [(numberofbond)\times D(bondbroken)]}-{\displaystyle \sum [(numberofbond)\times D(bondformed)]}$

The relative number (in moles) of each of the reactants and products get balanced.
