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 barium hydroxide endothermic or exothermic?
it is exothermic since it produces energy. if endothermic it would use up energy.
Is rusting metal exothermic or endothermic?
Rusting metal is an exothermic process because it releases heat as it occurs. This process involves the reaction of iron with oxygen in the presence of water to form iron oxide (rust), and this reaction releases energy in the form of heat.
Which compound forms exothermically?
An exothermic reaction releases heat energy to the surroundings. Compounds like combustion reactions (e.g. burning of wood or gasoline) typically release heat during their reaction, making them exothermic.
What is true about energy in an ordinary chemical reaction?
In an ordinary chemical reaction, energy is conserved, meaning the total energy before and after the reaction remains constant. This energy can be released or absorbed in the form of heat, light, or other forms, depending on whether the reaction is exothermic (releases energy) or endothermic (absorbs energy). Additionally, the energy changes often involve breaking and forming chemical bonds, which requires or releases energy. Overall, the law of conservation of energy dictates that energy is neither created nor destroyed, only transformed.
Is the reaction between caesium and water exothermic or endothermic?
The reaction between caesium and water is exothermic, meaning it releases heat. This is because when caesium reacts with water, it forms caesium hydroxide and hydrogen gas, releasing energy in the process.
What is the difference of endothermic reaction from exothermic reaction?
Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature, while exothermic reactions release heat to their surroundings, causing an increase in temperature. In endothermic reactions, the products have more energy than the reactants, whereas in exothermic reactions, the products have less energy than the reactants.

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.
What kind of reaction is ammonium nitrate and sodium hydroxide?
The reaction between ammonium nitrate and sodium hydroxide is a double displacement reaction, also known as a metathesis reaction. This reaction forms water, sodium nitrate, and ammonium hydroxide as products.
Why is the reaction between water and acid exothermic?
The reaction between water and acid is exothermic because it releases heat energy as it forms new chemical bonds in the products. The formation of these bonds is more stable and has lower energy than the reactants, resulting in a net release of energy in the form of heat.
What is the overall energy change that occurs when a solution forms?
The overall energy change that occurs when a solution forms is the sum of the energy required to break the solute-solute and solvent-solvent interactions (endothermic process), and the energy released when solute-solvent interactions are formed (exothermic process). This results in either an endothermic or exothermic process, depending on the relative magnitudes of these interactions.
What compound forms during the reaction between elemental sodium and elemental chlorine?
Sodium chloride (NaCl) forms during the reaction between elemental sodium (Na) and elemental chlorine (Cl). This reaction is highly exothermic and releases a significant amount of energy. Sodium chloride is a common table salt used in cooking and food preservation.
