The formula to calculate the Standard Enthalpy is:
\[ Es = \Delta H_p - \Delta H_r \]
Where:
Standard Enthalpy is a measure of the total heat content in a chemical reaction at standard conditions. It is calculated by subtracting the sum of the change in enthalpy of the reactants from the change in enthalpy of the products. This value helps in understanding the energy changes that occur during chemical reactions.
Let's assume the following values:
Using the formula:
\[ Es = 500 - 300 = 200 \, \text{J} \]
The Standard Enthalpy is 200 J.
Let's assume the following values:
Using the formula:
\[ Es = 1000 - 800 = 200 \, \text{J} \]
The Standard Enthalpy is 200 J.
