Presentation transcript:

The study of energy and its interconversions… Thermodynamics

The energy change in a process is constant and irrespective of whether the reaction takes place in one step or many… Hess’s Law (First Law of Thermodynamics)

Thermodynamics Direction Speed (kinetics) (The driving force for a spontaneous process is an increase in the entropy of the universe) Direction Speed (kinetics)

Entropy is a thermodynamic function which describes the number of arrangements available to a system existing in a given macrostate.

Nature spontaneously proceeds towards states having the highest probability of existing.

There are many more states available in the universe that would be described as disordered (as opposed to ordered)

Therefore, the universe will tend towards disorder!

The entropy of the universe is increasing.
