Equilibrium

Question 1

The measure of the distribution of energy throughout a system or btwn a system & its environment is known as ?

Answer 1

Entropy (J/K*mol)

Question 2

What is the role served by the reaction quotient Q?

Answer 2

Q than products)
Q=Keq: rxn is in dynamic equilibrium
Q>keq: forward rxn has exceeded equilibrium (conc. of products > than reactants)

Question 3

What are the essential characteristic of the law of mass action ?

Answer 3

1. Conc. of pure liquids & solids is negligible
2. Keq is temp dependent
3. Keq>, farther right equilibrium position
4. if one direction =keq, than opposite direction is 1/keq

Question 4

How do dynamic & static equilibrium differ ?

Answer 4

DE: forward & reverse rxns still occuring
SE: forward & reverse rxns stop due to going @ same rate (no net change in conc. of products or reactants)
