Homework Help: Chemistry

Posted by Hannah on Saturday, March 3, 2012 at 10:25pm.

For the reaction system, 2 H2O(g) + O2(g) == 2 H2O2 (g), the equilibrium concentrations are
(H2O2) = 0.120 M; (H2O) = 0.860 M; (O2) = 0.330 M.
Calculate the value of Kc for this reaction.

A. 0.423
B. 0.872
C. 0.0590
D. 1.31
E. 2.51


I did 0.120 / 0.860 X 0.330 = 4.4228 = 4.23.

Did I do this correctly?
