The industrial method currently used to produce butan-2-ol is the hydration of but-2-ene.
C₄H₈(g)+H₂O(g) → C₄H₁₀O(g)
Use Hess's Law and the equations given below to calculate the enthalpy change, in kJ mol¹, for the production of butan-2-ol by hydration of but-2-ene.
4C(s)+4H₂(g) → C₄H₈(g) ∆H=-7-1 kJ mol-1
4C(s) +5H₂(g) + O₂(g) → C₄H₁₀O(g) ΔΗ = -292-8 kJ mol-1
2H₂(g) + O₂(g) → 2H₂O(g) ∆H=-483-6 kJ mol-1
