Combustion reactions are exothermic
WebCombustion reactions are generally highly exothermic redox reactions between an oxidant and a fuel. The product formed in a combustion reaction is usually the oxidised fuel (which is mostly liberated in the gaseous state). This is often referred to as smoke. It is not uncommon for combustion reactions to be accompanied by flames. Weba) exothermic b) endothermic Q.4.
