Question
A calorimeter is calibrated by mixing two aqueous solutions each with a volume equal to 44.4 mL.
The reaction is known to produce 1,465 J of heat, and the measured temperature rise is 4.64 K.
Heat produced by the reaction is absorbed by the calorimeter and the resulting solution in it.
The same calorimeter is used in a subsequent experiment where 44.4 mL of 0.430 mol L-1 HCl are mixed
with 44.4 mL of 0.43 of NaOH. The temperature rises by 3.38.
Calculate the heat evolved by the reacting system in J
*be sure to include the correct sign in your answer*.
heat evolved (J) =
What is the enthalpy of the neutralization reaction in kJ/mol ?
Enthalpy of Reaction (kJ/mol) =
kJ/mol
