1. The problem statement, all variables and given/known data
consider the following reaction: 2H2O(i) <-> 2H2(g) + O2(g)
kc=7.3*10^-18 at 1000oC
The initial concentration of water in a reaction vessel is 0.055 mol/L. What is the equilibrium concentration of H2(g) at 1000oC?
2. Relevant equations
h20 h2 02
I 0.055 0 0
C -2x +2x +x
E0.055-2x 2x x
3. The attempt at a solution
The equation I got is:
-4x^3+2.92*(10^-17) x^2 -1.606*(10^-18) x +2.20825*10^-20 =0
How do I solve it if it is a cubic function?
