Chemical reaction bonds broken
WebIn a particular chemical reaction 3 bonds are broken and 4 bonds are formed. Based only on this information, which of the following is true? a. The reaction has a high activation energy. b. The reaction is endothermic. c. the reaction is exothermic. d. We cannot determine which of the above is true. D WebAn overall chemical reaction that breaks bonds and forms new ones can be endothermic (absorbing heat) or exothermic (releasing heat), depending on how much energy is absorbed and produced by the decomposition and synthesis reactions. What is released when bonds are broken to create heat? Exothermic reactions release energy in the …
