Question

How is Gibbs' free energy related to enthalpy? My biology textbook talks about the former, whereas my chemistry textbook talks about the latter, but they seem similar.

Answer 1

Gibbs free energy is the energy released from a reaction or absorbed by a reaction depending if it is an endothermic reaction (reduction reaction) or exothermic reaction (typically oxidation reaction).

Whereas enthalpy states that the amount of energy in a closed system is constant energy can be neither created or destroyed.

Answer 2

Your definition of enthalpy is the first law of thermodynamics. I don't think that's right, although I'm sure that law is a factor.

Answer 3

They are related in that when chemicals break down or recieve enough energy to react the energy in the system remains constant but the types of energy present in the system shifts

Answer 4

entropy is the law that states the universe is increasing in disorder.

Answer 5

my definition is correct

Answer 6

I think you are just confused

Answer 7

Enthalpy is a measure of the total energy of a thermodynamic system

Answer 8

so yeah I guess I messed the definition up a little bit but it still applys

Answer 9

Alright, I'm just looking for a better way of understanding them. I can get the definitions of each one pretty easily.

Answer 10

well
An example of an exothermic reaction
