Exothermic and Endothermic ReactionsState that an exothermic reaction transfers thermal energy to the surroundings leading to an increase in the temperature of the surroundingsState that an endothermic reaction takes in thermal energy from the surroundings leading to a decrease in the temperature of the surroundingsState that the transfer of thermal energy during a reaction is called the enthalpy change, ΔH, of the reaction. ΔH is negative for exothermic reactions and positive for endothermic reactionsInterpret reaction pathway diagrams showing exothermic and endothermic reactionsDefine activation energy, Ea, as the minimum energy that colliding particles must have to reactDraw and label reaction pathway diagrams for exothermic and endothermic reactions using information provided, to include:(a) reactants(b) products(c) enthalpy change of the reaction, ΔH(d) activation energy, EaState that bond breaking is an endothermic process and bond making is an exothermic process and explain the enthalpy change of a reaction in terms of bond breaking and bond makingCalculate the enthalpy change of a reaction using bond energies
