When an endothermic reaction occurs and there is an overall increase in entropy, it means that energy is absorbed from the surroundings and the disorder or randomness of the system increases.
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.
The difference can be clarified by entropy (the second rule of thermodynamics).The reaction is more spontaneous with higher entropy, for the reactions that occur spontaneously the entropy is higher than for the ones that do not.
The entropy increases in this reaction, as the solid reactant (I2(s)) is becoming a gas (I2(g)), which represents a higher degree of disorder and randomness on a molecular level. The increased entropy contributes to the spontaneity of the reaction.
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.
The entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
Entropy increases. In a reaction comprised of sub-reactions, some sub-reactions may show a decrease in entropy but the entire reaction will show an increase of entropy. As an example, the formation of sugar molecules by living organisms is a process that shows decrease in entropy at the expense of the loss of entropy by the sun.
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.
When a endothermic reaction happens, you may be able to notice a drop in temperature. Sometimes, endothermic reactions need more energy than they can get from their surroundings. In those cases, energy must be added as heat to cause the reaction to take place.Hope this helps.
An endothermic reaction need heat to occur.
This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced

Yes, in an exothermic reaction, energy is released from the chemicals into the surroundings in the form of heat. This results in a temperature increase in the surroundings.
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.
The entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
When energy is transformed, entropy can either increase or decrease. For example, in many energy transformations, such as combustion or chemical reactions, entropy tends to increase due to the dispersal of energy. However, in some processes, such as certain phase changes, entropy can decrease.
In an endothermic reaction, energy is absorbed from the surroundings, causing the surroundings to feel cooler. This is in contrast to an exothermic reaction, where energy is released into the surroundings, causing them to feel warmer.
