define formation of CO2 with Hess law
Answers
reaction using Hess’ law.
The standard molar enthalpies of formation DBH— o are impor-
tant thermodynamic tabulation quantities for calculating stan-
dard reaction enthalpies of any arbitrary reaction. They are
defined as the heat of reaction occurring in the direct formati-
on of one mole of the pertinent pure substance from the sta-
ble pure elements at constant pressure.
For spontaneous and quantitative reactions, e.g. the conversi-
on of carbon and oxygen to CO2, the stand- ard enthalpies of
formation can be measured directly using calorimetry.
Alternatively, they can be calculated from known enthalpies of
reaction using Hess’ law.
Answer:
Carbon Dioxide (CO2) is a gas with a molecular structure composed of two oxygen atoms and one carbon atom. It is an important greenhouse gas because of its ability to absorb infrared wavelengths. Carbon Dioxide, CO2, is a colorless, odorless, incombustible gas, present in the atmosphere and formed during respiration.
