Chemistry 12: Equilibrium

Open system is when

the reactants and products are free to escape

In an ocean system, reactions are considered to go to

completion

In an open system, reactions can only go in__direction

one

A closed system is when the reaction is allowed to take place in a___such that___reactions__products are___

vessel, neither, nor, lost

Equilibrium is occurred when you have___due to a__of__and__

constant visible properties, constant #, reactants and products

In a closed system, reactions can occurred in__direction

both

Forward Rate

R→P

Reverse rate

P→R

For a reaction at equilibrium, it will___or__appear that___is happening

physically, visually, nothing

The__and__reactions are occurring at the___rate

forward, reverse, same

Since the reactions are continually occurring, the overall reaction is considered to be at a___

dynamic equilibrium

The___does not have to equal to__, the__just have to remain__

[reactants], [products], concentrations, constant

If conditions change,___rearranges itself (or___) until a___is established

the equilibrium, shift, new equilibrium

It__matter if you start with___or___,___will be reached at that given temperature

doesn’t, all reactants, all products, equilibrium

Rate of___or___depends upon__ratio

decomposition, formation, mole

There are two ways to graph equilibrium

Rate vs time and amount vs time

All chemical reactions favor the side with___P.E, therefore reaction tends to toward__or lower energy

lower, minimum enthalpy

Entropy is the amount of ___in the system. All systems tend toward__

randomness, maximum entropy (maximum messiness)

Least to most messiness

solid → pure liquids → solutions → gas

The order shows from the__to the__# of particles

least, most

All chemical systems tend toward___and___

minimum enthalpy, maximum entropy

Le Chatelier’s Principle is when a__is placed on an equilibrium system, the equilibrium will__to__or counteract the applied stress resulting in a new___

stress, shift, offset, equilibrium

Shift

The rate that is initially faster
