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)0.5
K3(K₁+K₂)/2
K3 = K₁.K₂
K3 = (K₁.K₂)2

Chemical Reaction Engineering
The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the

Collision frequency increases
Fraction of molecules having threshold energy increases
Increased temperature reduces the activation energy
Value of threshold energy decreases
