An experiment to measure the enthalpy change for the reaction of aqueous copper(II) sulfate, CuSO4(aq) and zinc, Zn(s) was carried out in a coffee cup
calorimeter as follows.
Cu2+(aq) + Zn(s) → Cu(s) + Zn2+(aq)
50.0 cm3 of 1.00 mol dm–3 copper(II) sulfate solution was placed in a
polystyrene cup and its average temperature after three readings was noted to be
25OC and the zinc powder was added . The final temperature was noted to be
91.5 OC. Calulate the heat of the reaction in kJ
