THERMODYNAICS

Question 1

are self-driven reactions; they take
place immediately without any
assistance from external source. They
have the potential to proceed
without any help from outside.
Spontaneity in chemical reactions is
also unidirectional.

Answer 1

Spontaneous Reaction

Question 2

“that the state of entropy of the entire
universe as an isolated system, will
always increase over time. The second
law also states that the changes in the
entropy in the universe can never be
negative.

Answer 2

SECOND LAW OF THERMODYNAMICS

Question 3

One of the goals of chemists is to be
able to predict if a reaction will be
spontaneous. Temperature plays an
important part. A thermodynamic factor
that considers the entropy and
temperature of the reaction would be
the best indicator of spontaneity

Answer 3

GIBBS FREE ENERGY

Question 4

is the principle
that when a stress is applied to a
chemical system at equilibrium, the
equilibrium will shift to relieve the
stress. In other words, it can be used
to predict the direction of a
chemical reaction in response to a
change in conditions of
temperature, concentration, volume,
or pressure.
