chem equilibrium system 1問

Yes, if you are at cert. level. Chem equilibrium is not required
It deals with reversible chemical reactions such as the following reactions.
(a)CH3COOH + H2O ----> CH3COO- + H3O+ acid-base
For example weak acid partially ionized involves equilibrium
(b)PCl5 ------> PCl3 + Cl2 homogenous (1 phase involved)
(c)H2O (l) ------> H2O(g) phase
基本上要用相向箭咀,但這個版面出不到

During the reaction both reactants and products are present. But the concentration of reactants or product depend on the value of K, the equilibrium constant. If the value of K is large, this connotes more product formed and via versa. Actually equilibrium has different types
acid-base, electrochem, phase and precipitation Usually calculation is involved.


In equibilium,following conditions must fulfil
(1)in a closed system.
(2)leave the system for several days until equilibrium set up
(3)temperature must be at optimium value, so that equilibrium can set up quickly.

I hope you can understand what I have written.
