In an experiment, you are using Hess's Law and calorimetry to determine the molar enthalpy for the neutralization of solid potassium hydroxide: KOH(s) + HBr(aq) → H,O(1) + KBr(aq) In order to use Hess's Law you must calculate molar enthalpy changes for two other known reactions: (1) HBг(ag) + Kонад) —Н20() + KBrfaq) (2) КОНIS) - Кон аgд) a. In reaction (1), the following data was recorded: Observation Experimental Observations Quantity, of reactant 1 100-ml of 1.00 mol/L KOH(aq) Quantity of reactant 2 100-ml of 1.00 mol/L HBr(aq) Initial temperature 10 °C Final temperature 12.5°C Combine the volumes of quantity 1 and 2 to obtain the mass of the environment, assume the specific heat capacity of water. Calculate the molar enthalpy for the neutralization of KOH(aq). (1:3)
