Talk:Boudouard reaction

Endo or exothermic reaction
Hi, I wanted to clarify whether it's an endothermic or exothermic reaction. In fact DeltaH is positive so for me it's an endothermic reaction because Enthalpy variation is positive. I've seen this elsewhere in my bibliography on Boudouard Reaction. Nicolas22031998 (talk) 09:08, 9 August 2023 (UTC)
