What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
How do changes in energy and temperature influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.
What changes in an exothermic chemical change?
A change that releases energy in the form of heat to its environment.
Is candle wax melting exothermic?
no because when a substance changes its state of matter then it is NOT considered a chemical reaction or a chemical change.
Which physical state changes are EXOthermic?
Freezing and condensing.
When the temperature changes cause of a reaction is it exothermic or endothermic?
It is exothermic
How can you tell the difference between an endothermic and exothermic reaction?
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
What are the changes that are exothermic?
exothermic chemical reaction is any reaction that releases energy to the enviorementex: burning a candle (heat energy is released) eutralization reaction
If the temperature of a reaction increases what happens to the value of the equilibruim constant?
Equilibrium constant changes when temperature changes. For an endothermic reaction, the equilibrium constant increases with temperature while for an exothermic reaction equilibrium constant decreases with increase in temperature. Equilibrium constants are only affected by change in temperature.
What is the criteria in terms of temperature changes for exothermic and endothermic reactions?
Endothermic reactions draw heat from the reactants / products and the environment, so they tend to get cooler as the reaction proceeds. Exothermic reactions release heat to the reactants / products and the environment, so they tend to get hotter as the reaction proceeds.

If the reaction gets hot is it an endothermic or an exothermic reaction?
The reverse reaction is not always endothermic or exothermic, the reverse reaction is the opposite of whatever the initial reaction is, so if the reaction is endothermic, the reverse reaction is exothermic and vise versa.
Describe the two types of energy changes that occur in a chemical reaction?
An exothermic reaction and the change between potential and kinetic.
How do changes in temperature and energy influence chemical changes?
The reaction rate is dependent on temperature (increasing the temperature the reaction rate increase) and activation energy.

What is the most endothermic reaction?
The most exothermic reaction is nuclear fusion, which is the power of a hydrogen bomb. Nuclear fission is also extremely exothermic.An extremely exothermic chemical (as opposed to nuclear) reaction, although maybe not the most ever, is the so-called thermite reaction. Fe2O3 + 2Al ---> Al2O3 + 2Fe ΔH = -851.5 kJ/mol See the Related Questions and Web Links to the left of this answer for more information.
