CHEM1101 Midterm: Thermodynamics recap

Effect of Volume and Temperature Change on the System If we increase volume, there are more positions possible for the molecules. This results in more microstates, so increased entropy. If we increase temperature, the aver...

CHEM1101 Midterm: State Functions

State Functions Usually we have no way of knowing the internal energy of a system; finding that value is simply too complex a problem. However, we do know that the internal energy of a system is independent of the path by ...

CHEM1101 Study Guide - Midterm Guide: The Strongest, Intensive And Extensive Properties, Standard Hydrogen Electrode

Voltaic (Electrochemical) Cells In spontaneous redox reactions, electrons are transferred and energy is released. That energy can do work if the electrons flow through an external device. This is a voltaic (electrochemical...
