terms as we have done in the case of KC above.
The activity of pure solids and liquids is accepted to be exactly equal to 1.
Examples: 4.1 – 4.4,
Problems: 4.1 – 4.5, 4.7 – 4.12, 4.15, 4.16, 4.17, 4.19 – 4.21, 4.24 Le Chatelier Principle:
If a system in dynamic equilibrium is disturbed, the system will adjust itself
in such a way as to counteract, as far as possible, the effect of that change.
Types of disturbances to chemical equilibria we will consider are: (a)
change in volume, (b) change in pressure, (c) change in temperature, (d) change in
concentration or partial pressure.
(a) change in volume:
Consider the reaction AB(aq) W A+(aq)...
