Question

if a system already in equilibrium is catalyst any action​

Answer 1

**The addition of a catalyst would increase both the forward and reverse reaction rates, meaning the equilibrium is reached faster. So if the reaction is already at equilibrium there will be no effect on a concentration-time or moles-time graph.

**In the presence of a catalyst, both the forward and reverse reaction rates will speed up equally, thereby allowing the system to reach equilibrium faster. However, it is very important to keep in mind that the addition of a catalyst has no effect whatsoever on the final equilibrium position of the reaction.

**A chemical reaction is in equilibrium when the concentrations of reactants and products are constant - their ratio does not vary. Another way of defining equilibrium is to say that a system is in equilibrium when the forward and reverse reactions occur at equal rates.

**When additional product is added, the equilibrium shifts to reactants to reduce the stress. If reactant or product is removed, the equilibrium shifts to make more reactant or product, respectively, to make up for the loss.
