Reaction	Label	$Δ H_{Gas}^{‡}$ ${\rm{\Delta }}H_{{\rm{Gas}}}^\ddag$	$Δ H_{2 H_{2} O}^{‡}$ ${\rm{\Delta }}H_{2{{\rm{H}}_2}{\rm{O}}}^\ddag$
CH₃CHO + H → CH₃CO + H₂	R1	18.5	19.6
CH₃CHO + H → CH₃CH₂O	R2	31.0	27.7
CH₃CHO + H→ CH₂CHO + H₂	R3	41.2	37.1
CH₃CHO + H→ CH₃CHOH	R4	47.3	48.1
CH₃CHO + H → CH₄ + HCO	R5	142.6	140.1

Notes. Using a gas phase ( $Δ H_{Gas}^{‡}$ ${\rm{\Delta }}H_{{\rm{Gas}}}^\ddag$ in kJ mol ⁻¹) and an explicit two H₂O model ( $Δ H_{2 H_{2} O}^{‡}$ ${\rm{\Delta }}H_{2{{\rm{H}}_2}{\rm{O}}}^\ddag$ in kJ mol⁻¹).
