# If a reaction system has come to equilibrium, the concentration of products can be increased by doing what?

By a miracle........

#### Explanation:

You have the equilibrium reaction.........

$A + B r i g h t \le f t h a r p \infty n s C + D$

And ${K}_{e q} = \frac{\left[C\right] \left[D\right]}{\left[A\right] \left[B\right]}$; now ${K}_{e q}$ may or may not be affected by temperature; and typically we specify standard conditions. But by definition, $\text{equilibrium}$, equality of forward and reverse rates, is A CONSTANT. We could add a catalyst so that the condition of equilibrium is achieved FASTER, but neither ${K}_{e q}$ nor the equilibrium concentrations could be altered.

Of course, in the given equilibrium, we could drive the reaction to completion, by removing the products $C$ and $D$, but here we manipulate an equilibrium, and do not change its value.
