  2. Endothermic process - Wikipedia

    en.wikipedia.org/wiki/Endothermic_process

    The opposite of an endothermic process is an exothermic process, one that releases or "gives out" energy, usually in the form of heat and sometimes as electrical energy. [1] Thus, endo in endothermic refers to energy or heat going in, and exo in exothermic refers to energy or heat going out. In each term (endothermic and exothermic) the prefix ...

  3. Energy profile (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Energy_profile_(chemistry)

    A reaction with ∆H°<0 is called exothermic reaction while one with ∆H°>0 is endothermic. Figure 8: Reaction Coordinate Diagrams showing favorable or unfavorable and slow or fast reactions [7] The relative stability of reactant and product does not define the feasibility of any reaction all by itself. For any reaction to proceed, the ...

  4. Exothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Exothermic_reaction

    [2] A strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬. Most of the spectacular chemical reactions that are demonstrated in classrooms are exothermic and exergonic. The opposite is an endothermic reaction, which usually takes up heat and is driven by an entropy increase in the system.

  5. Endothermic gas - Wikipedia

    en.wikipedia.org/wiki/Endothermic_gas

    Endothermic gas is a gas that inhibits or reverses oxidation on the surfaces it is in contact with. This gas is the product of incomplete combustion in a controlled environment. An example mixture is hydrogen gas (H 2 ), nitrogen gas (N 2 ), and carbon monoxide (CO).

  6. Exothermic process - Wikipedia

    en.wikipedia.org/wiki/Exothermic_process

    According to the IUPAC, an exothermic reaction is "a reaction for which the overall standard enthalpy change ΔH⚬ is negative". [4] Some examples of exothermic process are fuel combustion, condensation and nuclear fission, [5] which is used in nuclear power plants to release large amounts of energy. [6]

  7. Thermometric titration - Wikipedia

    en.wikipedia.org/wiki/Thermometric_titration

    The reaction of silver nitrate with chloride is strongly exothermic. For instance, the reaction enthalpy of Ag + with Cl − is a high −61.2 kJ/mol. This permits convenient determination of chloride with commonly available standard 0.1 mol/L AgNO 3. Endpoints are very sharp, and with care, chloride concentrations down to 15 mg/L can be analyzed.

  8. Thermochemistry - Wikipedia

    en.wikipedia.org/wiki/Thermochemistry

    Thermochemistry is useful in predicting reactant and product quantities throughout the course of a given reaction. In combination with entropy determinations, it is also used to predict whether a reaction is spontaneous or non-spontaneous, favorable or unfavorable. Endothermic reactions absorb heat, while exothermic reactions release heat ...

  9. Flow chemistry - Wikipedia

    en.wikipedia.org/wiki/Flow_chemistry

    As a result, endothermic and exothermic reactions can be thermostated easily and consistently. The temperature gradient can be steep, allowing efficient control over reaction time. Safety is increased: Thermal mass of the system is dominated by the apparatus making thermal runaways unlikely. Smaller reaction volume is also considered a safety ...
