The burning of carbon to form carbon dioxide is an example of a/an:
Endothermic reaction
Photochemical reaction
Exothermic reaction
Reversible reaction
Exothermic reaction
The combustion of carbon is an exothermic reaction because it releases a significant amount of heat energy into the surroundings. During this chemical process, carbon reacts with oxygen to form carbon dioxide, and the bond energy of the products is lower than that of the reactants, resulting in the dissipation of energy.
The combustion of carbon is an exothermic reaction because it releases a significant amount of heat energy into the surroundings. During this chemical process, carbon reacts with oxygen to form carbon dioxide, and the bond energy of the products is lower than that of the reactants, resulting in the dissipation of energy.
In the context of Geography and Environment, this reaction is the fundamental chemical process behind the release of carbon dioxide during the burning of fossil fuels, a primary driver of the greenhouse effect and global warming discussed in NCERT Geography Class 11.
Exothermic reactions are defined by a negative change in enthalpy (Delta H < 0).
Burning of fuels like coal (carbon) is a primary industrial source of heat and energy.
Combustion reactions always involve oxygen as a reactant and release energy in the form of heat or light.
Endothermic reactions (Option A) absorb heat from the surroundings, such as the process of photosynthesis.
Photochemical reactions (Option B) are initiated by the absorption of light, such as the decomposition of silver chloride.
Reversible reactions (Option D) can proceed in both forward and backward directions, whereas combustion is typically irreversible under standard atmospheric conditions.
The chemical equation for this process is C + O2 leads to CO2 + Heat.
C is correct тАФ The burning of carbon releases heat energy, making it an exothermic reaction.
In Physics, remember that energy released in combustion is often converted into work in internal combustion engines, linking Chemistry to the Laws of Thermodynamics.
