Hess’ Law
Hess’ Law:Work to be done:Find enthalpy change by measuring temperature change of a reaction.The temperature of 200ml water that I poured into the isolator was 23.0°C. To that I added 1.97g solid NaOH and let the reaction take place. After a while I measured the temperature to 24.9°C à rT = 1.9°C. The number of mole NaOH is 1.97 / 40 = 0.049 mol.
