Have you heard of Haber-Bosch process of production of ammonia. This is an example of the question you asked. If we apply the required heat in the beginning of the reaction we do not need to apply it again as its exothermic reversible reaction and will use the heat to continue the reaction. But the rate of reaction is not increased.
exothermic reactions1) Combustion: A combustion reaction is when oxygen combines with another compound to form water and carbon dioxide. These reactions are exothermic, meaning they produce heat. An example of this kind of reaction is the burning of napthalene:C10H8 + 12 O2---> 10 CO2 + 4 H2O
This is an exothermic reaction.
An exothermic reaction can produce a covalently bonded compound or an ionically bonded one. It depends on the starting reactants.
an exothermic combination reaction
This reaction is exothermic because there is a net RELEASE energy.
The reaction of sulfur and oxygen to produce sulfur dioxide is called combination or synthesis.
Heat is always released in exothermic reactions.
To produce water? Exothermic and very much so.Take a mixture, spark it and it will burn or explode. Heat energy is given off far in excess of whatever energy was needed to start the reaction.
It is the oxidation of Iron to Iron oxide. An exothermic reaction.
Thermite process is a procedure of welding using an exothermic reaction to produce a high temperature.
It will decrease as heat is removed from the environment and added to the products of the reaction.
The strong acid could cause an exothermic reaction (produce a lot of heat) Weak acid do the same, but do not produce such a strong exothermic reaction. Acid in Water might be a thrill Water in Acid could be rather unpleasant. Regards.
