Effects of temperature and pressure on exothermic and endothermic reaction?
An increase in temperature favours an endothermic reaction over an exothermic one as an endothermic reaction takes in the energy from the higher temperature more easily than the exothermic reaction gives out even more energy to the surroundings. Therefore an increase in temperature increases the level of completion and viability of an endothermic reaction, and the opposite for an exothermic reaction. An increase in pressure favours any reaction that forms fewer molecules from more molecules. It does not necessarily favour an exothermic or an endothermic reaction as it depends on the number of molecules on either side of the reaction. An endothermic reaction involves the breaking of bonds to a greater extent than an exothermic reaction, so an increase in pressure would, in a lot of cases, favour the exothermic reaction more than the endothermic reaction.
Is rusting metal exothermic or endothermic?
It is an exothermic reaction. However, rusting of iron liberates only a small amount of heat as compared to other forms of metal corrosion.
Boiling and evaporation are both forms of what?
Boiling and evaporation are both forms of changing liquids into gas. Boiling occurs when the liquid reaches its boiling point, while evaporation can occur at any temperature.
What always results in a chemical reaction?
a new compound is formed a change in temperature occurs during reaction,
Do KOH when dissolved in water conduct electricity?
Yes, because KOH is highly ionic in nature and water being polar in nature is a very good solvent for KOH and forms a solution. The reaction is heat generating and called Exothermic Reaction.
What is the difference of endothermic reaction from exothermic reaction?
An endothermic reaction requires heat to form products. An exothermic reaction produces heat when it forms products.

Does an exothermic reaction contain more chemical energy than reactants?
depends , if the reaction is endothermic or exothermic. if the reaction is endothermic , the energy needed to break the bonds is greater than the energy that forms bonds.and to break bonds you need thermal energy , meanwhile forming bonds gives off energy. now if the reaction is exothermic the energy given off the bonds form are greater than the enrgy needed to break them. you know if the reaction is exothermic or endothermic because exothermic have a negitave delta next to d eqn.while endothermic have a positive delta.
Does endothermic or exothermic get colder?
Yeah, endothermic means that the heat is basically sucked out of it... or released while in an exothermic reaction, the heat is gathered or taken in. Take for example hot gas in a glass container: if it is cooled down of placed into a tub of ice, the gas will condense and the gas forms into droplets of liquid on the sides of the container and then drops to the bottom once there's enough of it.
What are three forms of an exothermic reaction can take?
Heat, light, or sound.
Does calcuim oxide react with cold water?
Yes it does react. It forms Calcium hydroxide and makes the water hot. It is because the reaction between CaO and water is an exothermic reaction
What are two chemical reactions that require energy in order to occur?
This type of reaction is called ENDOTHERMIC REACTION.
Boiling and evaporation are both forms of what?
Boiling and evaporation are both forms of changing liquids into gas. Boiling occurs when the liquid reaches its boiling point, while evaporation can occur at any temperature.
Is the combustion of propane endothermic or exothernic?
In the presence of excess oxygen, propane burns to form water and carbon dioxide. When not enough oxygen is present for complete combustion, incomplete combustion occurs when propane burns and forms water, carbon monoxide, and carbon dioxide.
What always results in a chemical reaction?
a new compound is formed a change in temperature occurs during reaction,
What happen when ammonia and hydrogen chloride are mixed?
There is a reaction between them. It forms NH4Cl by reaction.
