Question

Transcribed Image Text:Which is the correct expression for K, for this reaction?
CH4 (g) + H2O (g) <-->
CO G) + 3 H2 (g)
O Kp is undefined for this reaction
O Kp = (Pco) (PH2)/ (PCH4) (PH20)
O Kp = (Pco) / (PCH4)
O Kp = (PCH4) (PH20)/ (Pco) (PH2)
%3D
O Kp = (Pco) (PH2)/(PCH4) (PH20)
Expert Solution

Step 1
• The given reaction is,
CH4(g) + H2O(g) ⇌ CO(g) + 3 H2(g)
where, CH4 and H2O are reactants while CO, H2 are products.
• We need to write the equilibrium constant in terms of pressure, Kp expression for the reaction.
