Determine the value of the equilibrium constant, K_new, for the reaction

6 X (s) + 3 O₂ (g) + 6 H₂ (g) 3 XH₃OH (g) + 3 XO (g), K_new =?

by making use of the following information:

XO₂ (g) + 3H₂ (g) XH₃OH (g) + H₂O (g), K₁ = 3

XO₂ (g) + H₂ (g) XO (g) + H₂O (g) K₂ = 10

2 X (s) + O₂ (g) 2 XO (g), K₃ = 9
