Chemical(ΔΗ) Heat Heat Lost/ Heat Released/ Heat Reactant/ ΔΗ Thermometer Gained Absorbed Product Value Reading Endothermic Gained Absorbed Reactant Positive Decrease Exothermic Lost Released Product Negative Increase Activation energy - the energy need to start an exothermic chemical reaction. For an exothermic reaction - add heat / spark / Heat Stoichiometry - Given an amount of A and the balanced equation with ΔH value. #A + B → C ΔH To calculate the heat used or released by the reaction g A x 1 mol A / Molar mass g A x ΔH kJ
