Delta H, S, and G

Determines if a reaction is spontaneous or not

Determines if a reaction is spontaneous or not

delta G of the reaction

A measure of disorder

delta S of the reaction

A measure of heat energy is released or required

delta H of the reaction

Gibbs Free Energy

delta G of the reaction

Entropy

delta S of the reaction

Enthalpy

delta H of the reaction

• is good for spontaneity

delta G of the reaction

• is good for spontaneity

delta S of the reaction

• is good for spontaneity

delta H of the reaction

Tell whether a reaction shifts left or right

delta G of the reaction

+= increasing disorder

delta S of the reaction

• exothermic

delta H of the reaction

-increasing order

delta S of the reaction

A measure of the amount of work a reaction can do on its surroundings (if spontaneous)

delta G of the reaction

units of J/mol * K

delta S of the reaction

related to the change in entropy of the surroundings

delta H of the reaction

how much work needs to be done on a reaction to make it go (if nonspontaneous)

delta G of the reaction

+= endothermic

delta H of the reaction

units are kJ/mol

delta H of the reaction

-= spontaneous

delta G of the reaction

+= nonspontaneous

delta G of the reaction

Units are kJ/mol

delta G of the reaction
