Free energy diagrams
The sign of the Gibbs free energy change (G) for a
about the direction of spontaneous
change in a system.
The equilibrium constant (K) informs about how far a
spontaneous process will proceed tow
Calculating Kc from equilibrium concentrations
Measure the concentrations of reactants and products
after the equilibrium has been reached: ceq
Substitute these equilibrium values into the
equilibrium constant expression to calculate Kc

While there are no absolutes when interpreting symbolism in literature, there
are certain symbols that writers commonly use. Some of the symbols have multiple
possible meanings and these meanings can be markedly different. This lis

The composition of a reaction mixture changes in the direction of
decreasing free Gibbs energy.
When the minimum Gibbs free energy has been reached, the system is
What happens when the equilibrium is disturbed?
Entropy and probability
Spontaneous processes tend to proceed from states
of low probability to states of higher probability
Spontaneous processes tend to disperse energy
Entropy and entropy change

Question 6 I think is B, not C. Each of the nitrogen atoms are attached to 3 different

Both chemical reactions and physical change
occur in a system in one particular direction
only under particular conditions of
temperature and pressure.
The system moves to a more stable state.
Such a process is said to be spontaneous.
Entropy (S) describes the number of equivalent ways that
energy can be distributed in the system.
