Reactions are all about the formation and the breaking of bonds between atoms. The formation of bonds within a system causes energy to be released whilst the breaking of bonds requires energy to be applie...

Ionic Bonding 

Ionic bonding occurs between positive ions (cations) and negative ions (anions), which are attracted to each other through their oppisite charges. The resulting comp...

By defintion, Le chatelier's principle states that if a reaction at equilibrium (i.e a reversible reaction) is subject to a change in concentration, pressure or temperature the system will act in a way to...

An ionic bond if formed from the transfer of electrons from the outer shell of atoms. The donor of the electrons becomes positively charged as it has more protons than electrons, and so is called a cation...

Overall the closed system will behave by Le Chantelier's Principal where the equilibrium moves to minimise change.

So in the first case increasing the pressure will move the equilibrium to the righ...
