What else can I help you with?
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.
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.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
What is the difference between endothermic and exothermic change?
Endothermic reactions absorb heat from the reactants, i.e , the vessel or beaker in which the reactions have happened will be cool to touch........ Whereas in exothermic reactions, Heat will be given out and the vessel will be hot to touch..........
Is freezing an example of endothermic or exothermic change?
Freezing is an exothermic process because heat is released when a substance changes from a liquid to a solid, lowering the temperature of the surroundings.
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.
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.
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.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
How do you distinguish exothermic and endothermic processes?
Exothermic processes release heat to the surroundings, causing a rise in temperature, while endothermic processes absorb heat from the surroundings, leading to a decrease in temperature. This distinction is often observed through changes in the energy content of a system – exothermic reactions have a negative change in enthalpy, while endothermic reactions have a positive change in enthalpy.
What is the difference between endothermic and exothermic change?

How do you classify a chemical reaction?
Chemical reactions can be classified based on the type of reaction (e.g., synthesis, decomposition, single replacement, double replacement) or the energy changes involved (e.g., exothermic, endothermic). Classification helps in understanding the underlying principles and predicting the products of reactions.
How exothermic and endothermic relate to responding to external changes?
Exothermic and endothermic both have to adapt to the climate changes. For example exothermic need to move in the sun or light source when they are cold and move to a cool place when they are hot. Endothermic have to let their body temperature warm up by being in the warmest place possible, when they are cold they instantly start trying to warm up automatically.
What is given off in all energy changes?
energy is released which makes it hotter because it is an exothermic reaction, or energy is absorbed which makes it colder and an endothermic reaction =]
