# How can I find the equilibrium constant of a reversed reaction?

Invert it....

#### Explanation:

We consider....

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

And ${K}_{\text{eq}} = \frac{\left[C\right] \left[D\right]}{\left[A\right] \left[B\right]}$

But CLEARLY....

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

And ${K}_{\text{eq reverse"=([A][B])/([C][D])=K_"eq}}^{-} 1$
