Thermodynamics deals only with the ____________scale response of a system which we can observe and measure in experiments.
large
Small
The second law of thermodynamics says:
Energy can neither be created nor destroyed. It can only change forms.
The entropy of an isolated system not in equilibrium will tend to increase over time, approaching a maximum value at equilibrium.
This quantity is the energy associated with a chemical reaction that can be used to do work, and is the sum of its enthalpy (H) and the product of the temperature and the entropy (S) of the system.
Gibbs Energy
Entropy
Fugacity
Dg < 0
Non- spontaneous reaction
Spontaneous reaction
Equilibrium
If the equilibrium state is _________, the system will return to that state when a small disturbance is imposed upon it.
Refers to a condition in which the state neither changes with time nor has a tendency to spontaneously change
Steady State
Equilibrium
Equilibrium can only occur in a _________ system.
Open
Closed
Mention the 4 types of equlibrium
The Second Law of thermodynamics can be expressed in terms of :
Entropy
Entalpy
Energy
Irreversible processes are...
Non spontaneous
Spontaneous
€For any reversible process, the entropy of the universe remains_________, while for any irreversible process, the entropy of the universe_______”.
Stable
Unchanged
Minimum
Diminishes
Increases
It is a measure of chemical potential in the form of 'adjusted pressure.' It directly relates to the tendency of a substance to prefer one phase (liquid, solid, gas) over another.
Entalpy
Entropy
Fugacity
Gibbs Energy
