What is the enthalpy of a reaction?
The amount of energy that is used or released as heat in a reaction.
What is the use of heat as a convenient measurement of chemical energy in any reaction?
Energy is measured in joules. Sometimes the older unit "calorie" is used instead - this is a unit defined on the basis of heat, but it is still a unit of energy.
What is a heat reaction?
This the heat released during a chemical reaction.
What is heat of reaction of Diphosphorus Pentasulfide?
If you wanted to, you could ask what the heat of formation is of a given compound such as diphosphorus pentasulfide, but if you want to know about a heat of reaction, you have to specify a reaction. A compound is not a reaction.
How are exothermic reation different from endothermic reaction?
Exothermic reaction: with release of heat Endothermic reaction: with absorption of heat

What is the difference between heat of reaction and molar heat of reaction?
Heat of a reacion is the totall amount of heat a reaction produces. Molar heat of a reaction is the heat produced/mol if you have the molar hear of the reaction you can calculate the heat of the reaction based on the moles of reactants you have
What is heat of the reaction is releasesd?
If heat from a reaction is released, it is an exothermic reaction.
What is a chemical reaction that absorbs heat?
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
What is the type of heat reaction which occurs when heat is given off by the reaction?
Heat is released during an exothermic reaction.
What is a heat reaction?
This the heat released during a chemical reaction.
How are endothermic reaction different from exothermic reaction?
Exothermic reaction: with release of heat Endothermic reaction: with absorption of heat
How does temperature affects reaction rate?
if the reaction is exothermic (creates heat) then adding heat will cause the reaction to run in the reverse direction if the reaction is endothermic (requires heat) then heat will speed it up
What happens in an endothermic reaction?
An endothermic reaction need heat to occur.
A reaction that absorbs energy is called?
Endothermic-take in Heat, as opposed to exothermic which gives off heat-like a fire or explosion.
How is heat included in the equation of an exothermic reaction?
Heat is written as a product of the reaction (apecs answer)
