A(g) + B (g) ↔ C (g) + D (g) Suppose that the concentrations of these gases in an equilibrium mixture were [A] = 0.5 M [B] = 4.0 M [C] = 6.0 M [D] = 8.0 M How many moles of C would have to be added to the mixture to raise the equilibrium concentration of A to 1.0 M?

OpenStudy (photon336):

@Lena772 I feel that for this problem you could set it up and find what the Kc value is because you're given the equilibrium concentrations. \[Kp = \frac{[C][D] }{ [A][B] }\]

OpenStudy (lena772):

48/2 Kp=24

OpenStudy (photon336):

let's think about this more, we are being told that we need to raise the concentration of A

OpenStudy (photon336):

clearly this value for Kp since it's greater than 1 suggests that the equilibrium favors the products.

OpenStudy (lena772):

yes should i do an ICE table?

OpenStudy (photon336):

yes I think so

OpenStudy (photon336):

My thoughts are that you would need to do an ice table, because in order for the concentration of A to increase Q > K and the equilibrium would have to shift to favor the reactants

OpenStudy (photon336):

BTW where did you get this question from it's very thought provoking

OpenStudy (lena772):

Chem21labs.com is the platform where all my G. Chem II course homework is. @Photon336
