Chemistry - Energy of Bonding - Regents Review

  1. 1. BONDING cont… By Monique Gordon Energy of Bonding:Endothermic – Reaction 1(endo): CD + 100kJ C+D • heat is a reactant • heat is absorbed Reaction 2 (exo): A + B AB + 100kJ • breaking a bond Reaction 3: E + B EB + 100kJExothermic – Reaction 4: F + G FG + 400kJ • heat is a product Which bond is more stable, EB or FG? FG, because it takes more energy (300kj more) to • heat is released break the bond than EB. • making a bond • less potential energy • bond is more stable www.nyschemistry.net
