Chapter 20 Chemistry

20.1
You can try to chemically synthesize petrochemical energy

materials.

20.2
Sugar cane juice can be synthesized into decomposable plastics/

biodegradable polymers.

20.3

Decomposable plastics/ Biodegradable polymers are about,
biochemistry.

20.4

P1V1/T1 = P2V2/T2 leads to PV= nRT
P = Pressure Pressure V = Volume Capacity T = Temperature

The volume rises and the temperature drops. The temperature
rises and the volume rises. (volume expands as temperature
increases)

Therefore, there are two relationships between temperature and
volume, proportional and inverse,

So the absolute gas formula above is incorrect.

20.5

Kinetics Dynamics == -dC/dt = k [C]^n
Because we have to consider cost or efficiency

So –dC/dt = -dC/dt/[C input]
C = Concentration. = Chemical concentration.

We can have increasing reactant concentration rate but
decreasing reactant rate efficiency.
