1) The concentration of the reactants and products would be constant and from this property we can say that equilibrium has been established.  
In kinetics we use the equilibrium constant K which is related to equilibrium.  K gives an idea about how fast the reaction reaches equilibrium.  Examples are what we face in daily life.  If we add water to Calcium carbonate we find carbon di oxide emanates.  Or when you open bottle of a fizzy cool drink we can find equilibrium
2) Though equilibrium constant will not change due to addition of catalyst, we can say that because of catalyst both the forward and backward reactions speed up, allowing the system to attain equilibrium faster.
3) Equilibrium gets affected by temperature.  If temperature increases equilibrium shifts to right otherwise it shifts to left.  
Second property is measuring pressure.  Increase in pressure decreases the volume thus making shift to right.
So two properties are temperature and pressure
4) Co(H2O)62+(aq) + 4 Cl-(aq)  CoCl42-(aq) + 6 H2O(g)
Equilibrium constant = (CoCl4) (H2O)^6/(CoH2O)*(Cl)^4
=(200.7452)(18.05)^6/(76.95)(35.45)^4 = 57.12
For backward action K would be = 1/57.14 = 0.
