Whether a reaction is endothermic or exothermic depends on the direction that it is going; some reactions are reversible, and when you revert the products back to reactants, the change in enthalpy is opposite. The categorization of a reaction as endo- or exothermic … The opposite of an exothermic process is an endothermic process, one that absorbs energy in the form of heat. a. the combustion of gasoline in a car engine b. water condensing on a cold pipe c. CO 2 ( s ) → CO 2 ( g ) d. F 2 ( g )→2F( g ) An exothermic reaction gives off energy to the surroundings; like a fire giving off heat. Endothermic and exothermic reactions are chemical reactions that absorb and release heat, respectively.
Endothermic reactions take in energy and the temperature of the surroundings decreases. The chemical bonds of the hydrocarbons break and are replaced by the bonds of water and carbon dioxide. An exothermic reaction is a chemical reaction that releases energy through light or heat.It is the opposite of an endothermic reaction.. An exothermic reaction corresponds to the formation of more bonds, stronger bonds, or both. Combustion is always exothermic because the reaction releases heat. Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. Exothermic and endothermic reactions. Combustion _____. An endothermic reaction takes in energy from the surroundings; like a snowman melting. The heat required for the endothermic gasification reactions is suppled by the exothermic combustion reactions between the coal and oxygen. A good example of an endothermic reaction is photosynthesis. The term exothermic was first coined by Marcellin Berthelot. The concept is frequently applied in the physical sciences to chemical reactions, where as in chemical bond energy that will be converted to thermal energy (heat). That reaction is an exothermic reaction.In this type of enthalpy change, the enthalpy of the products is less than the enthalpy of the reactants. When a chemical reaction occurs, energy is transferred to or from the surroundings. There is usually a temperature change. When a chemical reaction occurs, energy is transferred to or from the surroundings. Combustion is a high-temperature exothermic (heat releasing) redox (oxygen adding) chemical reaction between a fuel and an oxidant, usually atmospheric oxygen, that produces oxidized, often gaseous products, in a mixture termed as smoke. Exothermic reactions transfer energy to the surroundings and the temperature of the surroundings increases. is an endothermic reaction is an exothermic reaction always produces flames occurs slow… Get the answers you need, now! Endothermic reactions take in energy and the temperature of the surroundings decreases. Combustion is an exothermic oxidation reaction, with materials such as hydrocarbons reacting with oxygen to form combustion products such as water and carbon dioxide.

Endothermic vs Exothermic reactions. Expressed in a chemical equation: reactants → products + energy.Exothermic Reaction means "exo" (derived from the Greek word: "έξω", literally translated to "out") meaning releases and "thermic" means heat. So, endothermic takes in heat from the environment and exothermic releases heat.
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
