free energy and entopy

temperature

 Increasing \________: Entropy increases when the \________ increases.

Entropy

The \________ (S) of a given system is the number of possible arrangements of the particles and their energy in a given system  In other words, it is a measure of how disordered or chaotic a system is.

Free energy and entropy Free energy

is the overall change of enegy for a process & It is free to do things

First law of thermodynamics

Energy can neither be created nor destroyed , but it can be changed from one form to another

+S  Increasing the number of moles

Having more molecules on the side of the product means that there is an increase in entropy

 Increasing temperature

Entropy increases when the temperature increases

Second law of thermodynamics

the energy of an isolated system never decreases

The feasibility of a reaction is determined by two factors, \-----

the enthalpy change and the entropy change

Thermodynamically unfavorable:

a process that doesn't produces free energy

Unspontaneous process

Thermodynamically unfavorable

Thermodynamically favorable:

a process that produces free energy

Spontaneous process

Thermodynamically favorable

Enthalpy , temperature and organization contributes to \------

free energy

Kinds of changes that increase disorder, or decrease predictability:

increasing heat , change state , cut in to smaller parts , increase num of moles

Second law of thermodynamics :

the energy of an isolated system never decreaes

t is more likely for a system to be disordered than to be highly ordered

TRUE

For a reaction to be spontaneous

,Gibbs free energy must be have a negative value

Crossover Temperature (Tc):

for every process that has one favorable & one unfavorable factor . At which ΔG\=0

ΔH (-) , ΔS (+) \n

favorable at any temperature

ΔH (+) , ΔS (-)

unfavorable at any temperature

ΔH (+) , ΔS (+)

favorable at high temperature

ΔH (-) , ΔS (-)

favorable at low temperature
