Chapter 4, Problem 4.16NP
Interpretation Introduction

Interpretation:

The annual enthalpy change for the photosynthetic carbon fixation over the land surface needs to be determined.

Concept Introduction:

The standard enthalpy change for a reaction ΔH0 is given in terms of the difference in the standard enthalpy of formation of the products and that of reactants.

i.e. ΔH0 = npΔHf0(products) - nrΔHf0(reactants)  ------(1)

Here, np and nr are the number of moles of the products and reactants
