betrokke, onthou qrxn = AH en onthou dat "per mol" beteken om te deel.) • In an acid-
base neutralization reaction between 50.0 mL of 0.5 M nitric acid (HNO3) and 50.0
mL of 0.5 M potassium hydroxide (KOH), Arxn was found to be -2500 J. The enthalpy
change (J) per mole of base is therefore ... (Hint: determine the relevant number of
moles of base, remember Arxn = AH and remember that "per mole" means divide.)

The enthalpy tell us about the heat that may be absorbed or evolved in a reaction. The ethalpy of this reaction is -100 kJ/mol.

What is enthalpy?

The term enthalpy deals with the heat that is absorbed or emitted in a reaction. The reaction equation is; HNO3 + KOH ----> KNO3 + H2O

Number of moles of HNO3 = 0.5 M * 50/1000 L = 0.025 moles

Number of moles of KOH= 0.5 M * 50/1000 L = 0.025 moles

Since the reaction is 1:1, then heat evolved = - (2500 J * 10^-3)/0.025 moles

= -100 kJ/mol
