Calculate Enthalpy Change of Neutralisation



Formula

The formula to calculate the Enthalpy Change of Neutralisation (ΔH) is:

\[ \Delta H = \frac{Q}{n} \]

What is Enthalpy Change of Neutralisation?

The enthalpy change of neutralisation is the heat energy change that occurs when an acid and a base react to form one mole of water. This reaction is typically exothermic, meaning it releases heat. The enthalpy change of neutralisation is an important concept in thermochemistry and is used to understand the energy changes that occur during chemical reactions. It is usually measured in kilojoules per mole (kJ/mol).

Example Calculation

Consider an example where:

Using the formula to calculate the Enthalpy Change of Neutralisation:

\[ \Delta H = \frac{50}{2} = 25 \text{ kJ/mol} \]

This means that the enthalpy change of neutralisation for this example is 25 kJ/mol.
