Thermodynamics
Chemical reactions proceed according to the rules of thermodynamics
• The law of conservation of energy – energy can be converted from one form to another but the total amount of energy is constant
• Entropy – the universe is becoming more chaotic
ACK!
Some constants
Gas constant: R = 8.315 Joules/K* mol or
1.9872 cal/K.mol
Faradays constant: F = 96485 Joules/Volt.mol or
23062 cal/Volt* mol
Thermodynamics
Energy: definitions
Energy – ability to do work
Energetics – energy transfer
Types of energy
• Potential – trapped energy
• Kinetic – energy of movement
Energy Categories: more definitions• Radiant energy – energy released from one
object to another• Mechanical energy – energy to move objects
from place to place• Electrical energy – energy that results from the
movement of charged particles down a charge gradient
• Thermal energy – reflected in the movement of particles and serves to increase temperature
• Chemical energy – energy that is held within chemical bonds
Energy Categories, Cont.
Animals rely on all five types of energy, which are interconvertible
