### Hmwrk 11.57 6th edition

11.57 A reaction mixture consisting of 2.00 mol CO and 3.00 mol H2 is placed in a 10.0-L reaction vessel and heated to 1200. K. At equilibrium, 0.478 mol CH4 was present in the system. Determine the value of Kc for the reaction
CO(g) + 3 H2(g) <--> CH4(g) + H2O(g) at 1200. K.

Is anyone else getting 3.909?

What numbers are you inputting? Don't forget to add the appropriate power for concentrations of substances that have coefficients in the chemical reaction. For me, I have Kc = [CH4][H2O]/[CO][H2]^3 = (.0478)(.0478)/(.152)(.157)^3 = 3.88.

Let me know if you have any questions about where these numbers come from since we have to make an ICE table.

how do you find the number of moles of H2O ?
