Chapter 9, Problem 9.105SP

Interpretation Introduction

Interpretation:

The ${\text{ΔH}}^{\text{0}}$ should be calculated in kilojoules.

Concept introduction:

• The photosynthesis is a reaction that is carried out by all the green plants. In this reaction the plants produce oxygen. Its balanced reaction is,

  ${\text{6CO}}_{\text{2}}{\text{(g)+6H}}_{\text{2}}\text{O(l)}\to {\text{C}}_{\text{6}}{\text{H}}_{\text{12}}{\text{O}}_{\text{6}}{\text{(aq)+6O}}_{\text{2}}\text{(g)}$

The ${\text{ΔH}}^{\text{0}}$ is the standard enthalpy changes of the reaction and it is calculated as the difference between the standard formation enthalpy changes of products and reactants.
