Chemical Reaction Engineering At a given temperature, K₁, K₂ and K3 are equilibrium constants for the following reactions 1, 2, 3 respectively. CH₄(g) + H₂O(g) ⇋ CO(g) + 3H₂(g), CO(g) + H₂O(g) ⇋ CO₂(g) + H₂(g) CH₄(g) + 2H₂O(g) ⇋ CO₂(g) + 4H₂(g) Then K₁, K₂ and K3 are related as: K3 = (K₁.K₂)2 K3 = K₁.K₂ K3(K₁+K₂)/2 K3 = (K₁.K₂)0.5 K3 = (K₁.K₂)2 K3 = K₁.K₂ K3(K₁+K₂)/2 K3 = (K₁.K₂)0.5 ANSWER DOWNLOAD EXAMIANS APP
