Entrhopt

Rate

Amoiunt of reaction per unit time

Molecules must

Collide with enough KE to react

Collision model

Must have enough energy to react

Activation energy

Min energy to react

Actrivated complex

Unsatbel momintary peak of energy

Factors that effect rate

Temp, catalyst, surface area, concintration

Catalyst

Speeds up reaction

enzyme

Catalyzes biological reactions

Inhibitor

slows or stops reaction

Elementary reaction

1 step reaction

Elementary reaction product

Intermediate

Reaction mechanism

Series of elementary reactions leads to overall reaction

Reversable reaction

Conversion of reactants to products and the conversion happen simolutaniously

Doubble arrow

Reaction reversable

Le chatelier principle

stress applied to system changes to relive stress

concintration

Addign more reactant produced more product

Temp

Increasign causes shirt to direction of heat

pressure

Chnages in pressure will only effect gas

Added to system

Away

Removeed from system

tward dremovced component

Keq

Equilibrium constant

KEq expression

Product/Reactant

2nd law of thermodynamics

any spontaneous process of disorder of universe

Keq 1>

reactants favored

Keq 1

Equal

Favorable reaction

spontanous reaction

enthropy

measure of order and disorder within a system

Law of disorder

Natural tendency for things to be mess y

Decrease enthropy favores

Non spontanous

High enthropy favores

spontaneous

Temp in enthropy

Increasein energy follows increase in temp

Crushing

Increases enthropy

Change of state

solid to liquid enthropy higher

Enthropt increases

when more products

Spontaions reactions

Natrurally

Nonspontanious

neeeds work

+S and -H

Alwayd spontaneouus

-S and +H

NEVER spontanipous

free energy

energy able to do work
