In Chapter 1 and Chapter 3 , we have learned that the rate of change of a species concentration is a summation of the rate of all the reactions it involved. For example, let’s consider a chemical pathway network (CPN) as shown in Fig. 4.1, which represents a system of two reactions: 2C + O 2 ⇒ 2CO and C + O 2 ⇒ CO 2 . This is what happens when carbon is burning in the air. Their rate coefficients can be estimated as: 4.1a https://www.w3.org/1998/Math/MathML" display="block"> k 1 = 3 × 10 12 exp ( − 1.51 × 10 5 R T ) 4.1b https://www.w3.org/1998/Math/MathML" display="block"> k 2 = 10 12 exp ( − 2.19 × 10 5 R T ) Figure 4.1 An example of a two-reaction system. The diagram illustrates a two-reaction system with circles represents carbon, oxygen, carbon monoxide, and carbon dioxide. Arrows connect the circles, indicate reaction rates and the flow between chemical species. https://www.w3.org/1999/xlink" content-type="colour" xlink:href=" https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003710134/067e4706-5e98-4459-9bbb-6226525ec302/content/fig4_1_C.jpg "/>
