Homework Statement


when steam was heated with excess carbon in a closed container to 1800kpa, the partial pressure of steam at equilibrium of steam was 318kpa, find Kp H2
,Kp CO and find Kp

Homework Equations



H2O(g) + C(s) -> H2(g) + CO(g)
<-

The Attempt at a Solution



I'm so confused because I only have 1 value,

I tried to find the initial moles of H2 but I can't.

Help is much appreciated.

If you know the partial pressure of one component, then the partial pressure of the other component must be the total pressure - partial pressure of the first component.

So the Kp of H2 and CO would be

1800-318= 1482?
