Question

Which will not appear in the equilibrium constant expression for the reaction below?

H2O(g) + C(s) <->H2(g) + CO(g)
1.[H₂O]
2.[C]
3.[Hz]
4.[CO]
Please help!​

Answer 1

[C]

Step-by-step explanation:

H20 does not appear when it is a liquid because pure water has a concentration of 1. However, you must notice that it is a gas in this problem so it must be entered.

The Reason C is not is because it is a solid. solids also have a concentration of 1 and are not necessary to calculate Ka or Kb
