CHEM 1202 Chapter Notes - Chapter 19: Thermodynamics, Equilibrium Constant, Ideal Gas
Document Summary
Know the 1st 2nd and 3rd law of thermodynamics. The first law of thermodynamics states that energy is conserved. Energy can be transferred between systems and surroundings. This gives it the ability to be able to be converted from one form to another. The total energy of the universe remains constant. Where e is the change in the internal energy of a system. W is the work done on the system by the surroundings, or on the surroundings by the. When q > 0 the system is gaining heat from the surroundings. When w > 0 the system is gaining work from the surroundings. Anything we do to lower the energy of the system raises the energy of the surroundings and vice. Spontaneous reaction occurs on its own without any outside assistance. Occurs in one direction only and the reverse is always nonspontaneous. Dropping a hard egg on the floor and it breaks on impact.
