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.
How does an exothermic reaction differ from n endothermic reaction?
An exothermic reaction releases heat to its surroundings, resulting in a temperature increase. In contrast, an endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature.
What happens during an exothermic reaction and how does it differ from an endothermic reaction?
During an exothermic reaction, heat is released to the surroundings, resulting in an increase in temperature. In contrast, an endothermic reaction absorbs heat from the surroundings, causing a decrease in temperature.
How do endothermic and ecothermic reactions differ?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature, while exothermic reactions release heat into the surroundings, causing a temperature increase. Endothermic reactions require energy input to proceed, while exothermic reactions release energy during the reaction.
Differentiate exothermic from endothermic reactions?
Exothermic reactions release heat energy to the surroundings, usually in the form of light or heat, resulting in a temperature increase. In contrast, endothermic reactions absorb heat energy from the surroundings, resulting in a decrease in temperature as the surroundings get colder.
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
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.
Why dissolving Ammonium nitrate(NH4NO3) in water is an endothermic although the temperature of the solution decreases?
The energy needed to support the endothermic reaction is supplied by the solution; thus the solution temperaturedecreases.If the reaction were exothermic, the solution temperature would increase.
How are exothermic and endothermic reactions different?
Exothermic reactions release heat to the surroundings, causing the surroundings to increase in temperature. Endothermic reactions absorb heat from the surroundings, causing the surroundings to decrease in temperature.

What two types of energy change can occur in a chemical reation?
Two types of energy change that can occur in a chemical reaction are endothermic or exothermic. An exothermic reaction causes an increase in temperature and an endothermic reaction causes a decrease in temperature.
How does temperature affect solubility of a substance which involves endothermic process in forming a solution?
endothermic substances absorb energy when dissolved. Therefore supplying energy(heat) externally will increase the solubility.
How do endothermic and ecothermic reactions differ?
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature, while exothermic reactions release heat into the surroundings, causing a temperature increase. Endothermic reactions require energy input to proceed, while exothermic reactions release energy during the reaction.
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.
How would the yield of ethanol at equilibrium change if the temperature was increased?
If you raise the temperature, the endothermic reaction will increase to use up the extra heat, therefore producing less percentage yield of ethanol and more of ethene and steam.
How can an endothermic reaction be spontaneous at room temperature?
An endothermic reaction can be spontaneous at room temperature if the increase in entropy of the system is large enough to overcome the energy input required for the reaction. This can happen if the products of the reaction have higher entropy than the reactants. As a result, the overall change in free energy can be negative even though the reaction is endothermic.
