Homework Statement
What is the value of Kc for the reaction H2(g) + F2(g) <=> 2HF(g) given that when 0.010 mol H2 and 0.050 mol F2 are added to a 1.00 L container, 0.0125 mol HF is present at equilibrium.
Homework Equations
The Attempt at a Solution
I'm confused about how to set up the ICE chart in this scenario. We have
H2(g) + F2(g) <=> 2HF(g)
.01... (.05) ... 0
-x ...-x ... 2x
.01-x...(.05-x) ... (.0125)
2x = .0125, x = .00625,
[.0125] ^2 / [.01 - .00625] [ .05-.00625] = 9.3 x 10 ^-6
Which is the incorrect answer, 9.51 ^-1 is right but I'm not sure how to get there. Any help would be appreciated.
