Enthalpy of neutralisation = – Q At constant pressure When neutralisation is carried out at atmospheric pressure, the thermometer measures the temperature rise, as depicted in the image. In this case, enthalpy change can be calculated as:
The standard enthalpy of neutralisation is the enthalpy change when one mole of aqueous hydrogen ions are neutralised by a base in dilute solution. For strong acids and strong bases, this value is – 57.33 kJ. This is because, independent of the strong acid or base, the neutralisationreaction...
if the heat is transmitted to a system at a steady pressure, the enthalpy of the system will increase. q5. the change in enthalpy when 1 mole of the compound is formed under standard conditions is known as (a) standard enthalpy of neutralisation (b) standard enthalpy of formation (c ) ...
