Enthalpy is an energy-like property or state function-it has the dimensions of energy (and is thus measured in units of joules or ergs), and its value is determined entirely by the temperature, pressure, and composition of the system and not by its history.

The enthalpy change for the following reaction is -137 kJ. Using bond energies, estimate the C-C bond energy in C2H6(g). I need a correct answer please thank you. and if you can, properly explain how.

National and regional accreditations and certifications for each of our laboratories.

Enthalpy Energy Services was founded in 2017 as a professional engineering, field engineering, startup & commissioning and related field-testing services organization to the energy sectors. We offer turn-key solutions for new projects, retrofits, and upgrades.

Enthalpies of formation are set H values that represent the enthalpy changes from reactions used to create given chemicals. If you know the enthalpies of formation required to create products and reactants in an equation, you can add them up to estimate the enthalpy much as you would with bond energies as described above.

The enthalpy can be made into an intensive, or specific, variable by dividing by the mass. propulsion engineers use the specific enthalpy in engine analysis more than the enthalpy itself. How does one use this new variable called enthalpy? Let’s consider the first law of thermodynamics for a gas.
