Determine the molar enthalpy change for reaction 1

 

                            HCl(aq)  +  NaOH(aq)  ®  NaCl(aq)  +  H2O(l)              DH1 =

 

Using the solution procedure similar to that of the sample problem shown on page 2, calculate the molar heat of enthalpy, in kJ/mol HCl, of reaction 1 given the following procedure and data information.

  1. Measure 50.0 mL of 2.00 M HCl into the coffee cup calorimeter
  2. Measure 50.0 mL of 2.00 M NaOH into a glass beaker
  3. Collect the initial temperature of both solutions
  4. Add the 50.0 mL of 2.00 M NaOH into the coffee cup calorimeter all at once
  5. Use the thermometer to gently and continuously stir the mixture in order to disperse the heat evenly thorough the solution
  6. Continue to monitor the temperature until it maxes out. Record the highest temperature.
  7. Assume all solutions have a density = 1.03 g/mL and a heat capacity = 4.18 J/g×°C

 

Temperature data:   Temperature of both solutions before mixing:  21.9 °C

                                    Maximum temperature of the reaction mixture:  35.6 °C 

In the space below, show all calculation set-ups to determine the molar heat of enthalpy, in kJ/mol HCl, of reaction 1 (DH1).
