WebCombustion reactions are an example of irreversible reactions, in which K can take on enormous values. For example oil - which we can symbolize with C n H m {\displaystyle \scriptstyle C_{n}H_{m}\,\!} , or wood , burn in the presence of oxygen (O 2 ) to transform mainly into carbon dioxide (CO 2 ) and water (H 2 O ), releasing thermal energy ... A reversible reaction is a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously. A and B can react to form C and D or, in the reverse reaction, C and D can react to form A and B. This is distinct from a reversible process in thermodynamics. Weak acids and bases undergo reversible reactions. For example, carbonic acid:
