Equilibrium
... You can mix chemicals expecting to get a reaction but no products can be detected, you can say that there is no reaction. Reversible reactions occupy a middle ground between the theoretical extremes of irreversibility and no reaction. A catalyst speeds up both the forward and the reverse reactions e ...

Shifting Equilibrium
... An increase in the concentration of a reactant is a stress on the equilibrium system. Consider the following hypothetical reaction. A+B⇄C+D An increase in the concentration of A creates a stress. To relieve the stress, some of the added A reacts with B to form products C and D. The equilibrium is ...
