Spontaneity

Spontaneous process

a reactiont that happens on it’s own without any outside interference

higher entropy is favored because

it gives the universe more options

positive delta S means that

a reaction is spontaneous

Second Law of thermodynamics

In any spontaneous process there is an increase in the entropy of the universe

entropy of the system and entropy of he surroundings equals

entropy of the universe

If delta S of the universe is positive

the process is spontaneous

if delta S of the universe is negative

the reverse of the reaction is spontaneous

Gibbs Energy

an equation used to find the spontaneity of a reaction using temperature, entropy, and enthalpy

Derive the equation for delta G

OK

If delta G is positive

the reaction is non spontaneous

if delta G is negative

the reaction is spontaneous

delta h/ delta s is

the pivot point since it is equal to temperature

T =

delta H/ Delta S

If Delta G is zero

the reaction is reversible

Delta G of Rxn

(stoic)product - (Stoic)reactants

Delta G wants to be

negative because it gives the universe mor entropy and more options, making it spontaneous
