Part A. Determination of the Heat Capacity of the Calorimeter
After the experiment, what is the temperature final of the system?
It = 25.10 °C
Using the extrapolated Tf and your experimentally determined initial temperature Ti, calculate the change in
temperature AT for the reaction.
AT = T£ - Ti
AT = 25.10 °C – 20.00 °C
AT = 5.10 °C
Given the following information and the actual amount of reactant used in the experiment, calculate the
heat, q, (in Joules) produced by the reaction.
н (aд) + ОН (ag) — H:О (1)
AH° = -55.83 kJ/mol
q=nx AH
1.0 m x -55.83 kJ/mol = -55.83 kJ
q = -55830 J
(A.4) Using the equation, calculate the total heat capacity of the calorimeter, C, in J/°C.
C =- q/AT
55830 J/ 5.10 °C
C = 10974.06 J/°C
1. If the value of the heat capacity (C) calculated in Part A of the experiment were too high, what
effect would this have on your value for AH, the enthalpy changes for the reaction between
magnesium metal and hydrochloric acid? Be specific. Would your answer be too high, or too
low, and why?
