Exothermic equation
WebJan 16, 2024 · An exothermic reaction is a chemical reaction that produces heat (has a negative ΔH). In other words, the activation energy needed to initiate the reaction is less than the energy it releases. Examples of exothermic reactions include neutralization reactions, the Haber process, the thermite reaction, and combustion reactions. WebConducting endothermic and exothermic reactions in parallel in the same reactor can be extended to the manufacture of synthesis gas from natural gas. The reaction CH 4 + H 2 O → CO + 3H 2 is endothermic ( ΔH = 206 kJ/mol), while CH 4 + 0.5 O 2 ⇌ CO + 2H 2 is exothermic ( ΔH = –38 kJ/mol).
