Question

endothermic reaction explain and examples

Answer 1

Basically if we categorise the reaction on the basis of Enthalpy evolution ..the reaction will be of two types ...that are Exothermic and Endothemic reaction...

Here Endothermic reactions basiclly stands for the reactions that absorb heat or requires input of heat for the reaction to be happened at its casual rate and concentrations. ...basically this reactions gain heat from any source or from the system to process the reaction....

Eg:- PHOTLYTIC REACTION HEAT REQUIRED IN FORM OF SUNLIGHT...

2AgCl =======> 2Ag (solid form) + Cl2 (gas evolved out)...,,

Answer 2

Heya!

The answer!!

•ENDOTHERMIC REACTION•
The reactions in which energy is absorbed while the reaction takes place is known as Endothermic Reaction.

Almost all decomposition reactions are Endothermic Reactions .
For example:-

1. CaCO3--heat------> CaO + CO2

That is when calcium carbonate is heated it gives Calcium Oxide and Carbon dioxide as it's products.

2.2H2O -----electricity---> H2+O2

That is when electricity is passed through water it gives Hydrogen Gas and Oxygen as it's products.



Hope this helps you!
