Draw the potential energy diagrams for an endothermic reaction and an exothermic reaction. Label the change in enthalpy, activation energy, transition state, reactants and products. Exothermic Endothermic 2. Complete the chart below about endothermic and exothermic reactions. Endothermic Exothermic Energy of the system Temperature of surroundings Energy of the surroundings Energy of products vs. energy of reactants? H value? 3. A calorimeter is set up to determine the specific heat of a peanut. The peanut is burned, and it provides enough energy to heat 30.0 g of water 12 ºC. The mass of the peanut is 2.50 g. How much energy, in joules per gram, is contained in the peanut? 4. Glucose (C 6 H 12 O 6 ) is burned in the body to produce energy. If the average can of soda contains roughly 40.0 g of sugar, how much energy (in kJ) will be produced when the glucose is combusted?
