Chapter 17 Notes: Equilibrium
Kinetics dealt with the speed/rate of reactions.
Equilibrium deals with
Given enough time the [reactant] and [product] will stop changing. When
this happens we say the reaction is at equilibrium.
This is not necessarily whe
Chapter 20 Notes: Thermodynamics
Spontaneous Change - one that occurs without
All chemical processes require energy (activation energy) to take place, but once a
spontaneous process has begun, no further input of energy is needed.
Nonspontaneous change -

Graphical Method to Determine Reaction Order from Integrated Rate Law
By plotting [A] and time in different ways we can determine the reaction order.:
Plot that gives a straight line:
This is just rearranging each integrated rate
