Consider the reaction in which HCl adds across the double bond of ethene: HCI + H2C=CH2 +H3C-CH2C1 The following reaction profile diagram represents the reaction. -Esz M EL Energy TAHUN C=C + HCl 1 - Reaction progress- =c H-C-C-Cl The bonds broken are stronger than the bonds formed. The bonds formed are stronger than the bonds broken. The reaction has two elementary steps The first step is the slow step This is an exothermic reaction overall There is only one elementary step and that is the slow step. This is an endothermic reaction overall The second step is the slow step
