Sam Christy Travis Dunn, Jarrod Googins He Li 11/06/07 Heats of Reaction Introduction: For this lab, we studied enthalpy change, also known as ΔH. This study is known as thermochemistry. As chemical bonds break and form in a chemical reaction, energy in the form of heat is either released or absorbed. ΔH is the energy change of a reaction. If heat is released, it is called exothermic, and ΔH is negative. If heat is absorbed, the reaction is called endothermic and ΔH is positive. Procedure: First is to collect all of the equipment that is needed to do the experiment. Then you take 50 mL of room temperature water and add it to the calorimeter and record the temperature in degrees Celsius. Then in a separate dish, heat 50 mL of water until it is 65 degrees Celsius. Once the water is heated to the right temperature, record the temperature. Then pour it into the calorimeter and record the temperature immediately and every ten seconds for one minute, then every 15 seconds for three minutes. Calculate
