Standard Enthalpies of Formation

Postby Brandon Tao 1K » Sun Jan 26, 2020 8:50 pm

Is the standard enthalpies... a constant or something that we will calculate?

Standard enthalpies of formation are given for certain molecules in the tables of the textbook. The standard enthalpy of a reaction though should be calculated.

The standard rxn enthalpy can be calculated by using the standard enthalpy of formation of all products and subtracting it by the standard enthalpy of formation of all reactants.

The standard enthalpies of formation is a value that is given for molecules and used to calculate the overall standard enthalpy of formation of a reaction.

The standard enthalpy of formation is a measure of the energy consumed or released when a substance is created under standard conditions, and can be calculated.
