When 10 g of KOH is added to 200 g of water in a ‘coffee cup calorimeter’, the temperature decreases from 27.39°C to 17.56°C.
a) Calculate qcalorimeter, in joules, assuming the specific heat capacity of the solution is the same as pure water: 4.186 Jg-1K-1.
b) Calculate ΔH, in kJ mol-1, if all the KOH dissolves in the water.
