Equilibrium

Question 1

What is Henry’s law

Answer 1

The mass of a gas dissolved in a solvent in proportional to the pressure if the gas above the solvent.

Question 2

Charactersitics of equilibria

Answer 2

1. Closed system
2. Dynamic in nature
3. measurable properties become contsnat
4. expression for C which is contant at constant temp
5. magnitude of constentration expression gives the indication of the extent of the reaciton

Question 3

Desrcube the state of quiliburbrum

Answer 3

The state where the measurable properties of a system such as concentration does not undergo any further change

Question 4

Law of mass action

Answer 4

The rate os a reaction is proportional to the product of contentrations raised to their stoichometric coefficients

Question 5

Law of chemical equilibrium

Answer 5

at given temp, ratio of forward and backward rate is constant

Question 6

Types of equilibrium

Answer 6

1. Homogenous equilibrium - same state
2. hetorgenous equilibrium - different states

Question 7

What happens when Q and K differ

Answer 7

1. Q>K : backward
2. Q<K : forward

Question 8

Le chatelier’s principle

Answer 8

If a system in equilibrium is subjected a stress, the equilibrium will shift such as to undo the effect of the stress
