Endothermic reaction or Endotermal
Endothermic reaction is a reaction that requires energy or absorb energy from the environment when the reaction occurs, this reaction generally produces dingin.atau temperature endothermic reaction is a chemical reaction that absorbs heat. Heat is taken from the environment so that the enthalpy increases. In endothermic reactions absorb energy systems. Therefore, the enthalpy of the system will increase, meaning that the enthalpy of the product (HP) is greater than the enthalpy of reactants (HR). As a result, changes in enthalpy (ΔH), namely the difference between the enthalpy of the product with the enthalpy of reactants is positive. So that:
ΔH = HP - HR Activation Energy ΔH> 0
From the graph above, can be seen that ΔH = HP - HR. Because HR is smaller than the HP. So ΔH> 0 Examples of endothermic reaction is a reaction to the melting of ice in a container. Examples of chemical reactions from ice melt events are: Sign (+) at 6.02 kJ on the left arrow indicates that the heat is absorbed by 6.02 kJ.
REACTION ice melts Thus, the reaction can also be written as follows: In reaction to the endoderm, heat (q) absorbed so that the positive enthalpy change (ΔH> 0). The reaction can be illustrated on the chart as well.
EXAMPLES OF REACTION endothermic Other examples of endothermic reactions in everyday life include: - Dissolution of sugar. If the sugar is dissolved, it can be felt there was little sense of cold when the glass is held
   The hand was cold when in contact with alcohol - Assimilation
 - Photosynthesis - Burning kerosene oil stove
 - Flame campfire when camping

endothermic reaction is a reaction that requires or absorbs heat, for example in their daily lives the most convenient way is to melt the ice event, or the manufacture of salt by heating from the sun, the wax is melted.
exothermic reaction is a reaction that occurs when a substance or object release / release of heat, in their daily lives are most easily seen is the condensation events, or the outside of the glasses full of cold water to wet the glass seolah2 leaking, but the air around the glass is a condensed ...
