Problem E15C.5(a)

Calculate the lattice enthalpy of CaO from the following data:

Step-by-Step Solution:
Step 1 of 3

Spencer Kociba CHEM 101 Lecture 11/15/16 THERMOCHEMISTRY ● Enthalpy ○ Represented as ΔH ○ Internal energy + pressure*volume ■ We will mostly be concerned with constant pressure. This is where the formula ΔH = ΔE + PΔV comes from ○ ΔH = q (enthalpy=heat gained or lost in the system) ● Properties of Enthalpy (ΔH ) ○ ΔH is directly proportional to mass ○ ΔH for a reverse reaction is equal in magnitude (quantity) but opposite in sign for the forwards reaction ○ Hess’s Law: ΔH is independent of the number of steps involved ■ If Reaction(1) + Reaction(2)=Reaction(3), then ΔH =3ΔH + 1H 2 ● Endothermic reactions ○ Gains heat from surroundings ○ ΔH =+ (ΔH >0) ○ Feels cold ○ E < E reactantsproducts ● Exothermic reactions ○ Releases heat to surroundings ○ ΔH =- ○ Feels hot ○ Ereactantsproducts ● A change in enthalpy results from a change in the potential energy of the reactants in forming products ● Calorimetry: measurement of quantity of heat exchanged during a chemical reaction ○ Bomb calorimeter ■ Constant volume used to measure heat and can withstand large amounts of pressure ■ Used to determine the energy content of foods and specific heat ○ Reactions done in an aqueous solution are done at constant pressure
