Find out the molar enthalpy change for the reaction

Reference no: EM13233347

In lab you mixed 50.0 mL of 1.0 M CH3CO2Na and 50.0 mL of 1.0 M HCl in a coffee cup calorimeter and determined ?T to be +0.543 °C. Using the same assumptions and approximations you used in lab, determine the molar enthalpy change (in kJ/mol) for the reaction below, assuming that CH3CO2H dissociates completely in water.

CH3CO2H(aq) + H2O(l) ? H3O+(aq) + CH3CO2-(aq)

Enter your answer in units of kJ/mol of CH3CO2H.

Lab assumptions:
solution specific heat 4.18J/gK.
Densities of H20 and solutions are 1 g/ml.
Calorimeter constant is 0.
Assume mass of solution needed for the calculation includes the mass of solute and solvent.
