A common laboratory reaction is the neutralization of an acid with a base. When 50.0 mL of 0,500 M HCİ at 25.0°C is added to 50.0 mL of 0.500 M NaOH at 25.0°C in a coffee cup calorimeter, the temperature of the mixture rises to 28.2°C. What is the enthalpy of the reaction (AH°rxn) per mole of acid? Assume the nixture has a specific heat capacity of 4.18 J/g-°C and that the densities of the reactant solutions are both .00 g/mL. HCI + Naci + (120 Na oH A. -670 J :50.0g (4.18)8.2-25.0) B. -1300 J C. -27 kJ D. -54 kJ
