Equilibrium Constant
« on: April 27, 2017, 12:10:40 PM »
The Keq for the reaction:

A + B   :resonance: AB is 3

What is the Keq for

4A + 4B  :resonance: 4AB?


How I am attempting to solve this:
Keq = [AB] / [A][ B]

My only thought is to use an ICE CHART

             A                  B                                    AB
I           ?                    ?                                     ?
C          -X                -X                                     +X
E                                                                     3

I am stuck here because I do not have an initial value and don't even know how to begin to relate this to the next equation. Someone help please!

Express both Keq using concentrations (no matter what they are) and just look at the formulas.

Keq = (AB) / (A)(B)
3 = (AB) / (A)(B)

Keq = (AB)4 / (A)4 (B)4

I have done that but since I have no values to plug in and I unsure where to go from here
