Caleb Jones Partner: Tripp Ferrence Heat of Reaction Lab In this experiment we determined the heat of reaction and for CH 3 COOH (acetic acid) and NaOH. The formula for the heat of reaction is q=mC T, where m is the mass of water, C is the specific heat, and T is the temperature change. We also determined the enthalpy change ( H ) for acetic acid. The value for q was determined through the use of a coffee cup calorimeter. A calorimeter is an experimental device that is well in- sulated, so ideally no heat escapes during the process of the reaction. The calorimeter measures the energy (q) absorbed when a reaction takes place. To determine H the equation H=q/moles of LR was used. The procedure followed for the experiment requires mixing acetic acid and sodi- um hydroxide and determining the heat absorbed during this reaction. We measured 40 mL of each solution and weighed each one. The weights were recorded and the NaOH was then poured into the Calorimeter. The initial temperature of the solution was taken,
