Answer 16

Repel

Question 17

Energy is neither created or destroyed but changed from one form to another

Answer 17

1st law of thermodynamics

Question 18

The total amount of energy remains constant however the amount of energy to do work decreases.

Answer 18

Th 2nd law of thermodynamics

Question 19

Gibbs Free Energy is…

Answer 19

The amount of energy in a system to do work

Question 20

Possible Gibbs

Answer 20

Products have more free energy than reactant

Question 21

Negative Gibbs

Answer 21

If the reactants have more free energy than produces

Question 22

Positive Gibbs and require input of energy (non-spontaneous)

Answer 22

ENDERGONIC

Question 23

Negative Gibbs and release energy (spontaneous)

Answer 23

EXERGONIC

Question 24

Entropy=

Answer 24

Influences the movement of molecules and adds a degree of disorder

Question 25

Energetic coupling is where=

Answer 25

A spontaneous reaction drives a non-spontaneous reaction

Question 26

Transition state is:

Answer 26

Where old bonds are breaking and new bonds are forming. Unstable and therefore has a large amount of free energy
