# League of Concentration

Chemistry Level pending

A few months after Joker's attack on Gotham city, the caped crusader receives a call from Commissioner Gordon, he tells Batman that the police headquarters has been compromised and he needs help. Batman arrives at the police headquarters, only to see it go up in a green flame.

In the reaction,
Ba + $$Cl_{2}$$ gives Ba$$Cl_{2}$$

If the concentration of :
Barium is $$10^{-5}$$ M
Chlorine gas is $$10^{-7}$$ M
Barium Chloride is $$10^{-13}$$ M

Can you help Batman calculate $$K_{eq}$$ for the reaction?
