What is Coulumb’s Law?
Like charges repel and opposite charges attract.
A charge is what type of energy?
Kinetic energy
Amount of charge flowing per unit time is ______ current.
electrical

What is Le Chatelier’s Principle?
When a system in a state of dynamic equilibrium is disturbed, it will react to re-establish the equilibrium condition.
What is it called when a system is in a state of equilibrium when there is a balance between reactants and products
Equilibrium constant
The balance in equilibrium constant is defined as what?
Thermodynamics
What is the meaning of K?
• as K increases, the reaction tends to increasingly favor products • as K decreases, the reaction tends to increasingly favor starting materials (the reverse reaction becomes more favorable)
The subscript of K eq denotes?
generic equilibrium constant
The subscript of K a denotes?
weak acid
