Best ResponseYou've already chosen the best response.0Wait, is the reaction at equilibrium?

Best ResponseYou've already chosen the best response.1Basically you are solving for Q and then your answer revolves around what answer you get for Q.

Best ResponseYou've already chosen the best response.0Okay, and then what?

Best ResponseYou've already chosen the best response.1Well the Kc given here states that the reactants are far more favored as it is far less than 1.

Best ResponseYou've already chosen the best response.1\[K _{c} =\frac{ [NO _{2}]^{2} }{ [N _{2} O _{4}]}\]

Best ResponseYou've already chosen the best response.0Yeah don't you get 4.3 x 10^2 when you do it that way?

Best ResponseYou've already chosen the best response.1since they have given us some concentrations calculate Kc for the given concentrations!

Best ResponseYou've already chosen the best response.04.3 x 10^2 does not equal Kc therefore you can conclude that the reaction is not at equilibrium

Best ResponseYou've already chosen the best response.0How? Can you show me your work?

Best ResponseYou've already chosen the best response.1Alright lets just set it up what it would look like to solve for Q in this situation. [.15]^2/[.5]= .045 which is 4.5x10^2 is what i got

Best ResponseYou've already chosen the best response.0Ohhh I see. I messed up.

Best ResponseYou've already chosen the best response.1which is in fact larger than the given Kc so what would have to happen to reach equilibrium?
