In an endothermic reaction, temperatures decrease because heat is absorbed from the surroundings to drive the reaction. Examples include photosynthesis, the evaporation of water, and the melting of ice.

What happens in an endothermic reaction and how does it differ from an exothermic reaction?

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.


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.


What happens when a reaction that is endothermic and results in an overall increase in entropy occurs?

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.


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 happens when dilute sulphuric acid is added to zinc granules . Is it an exothermic or an endothermic reaction?

When dilute sulfuric acid is added to zinc granules, a displacement reaction takes place, resulting in the formation of zinc sulfate and hydrogen gas. This reaction is exothermic, which means it releases heat energy.

What happens when delta h is positive?

When ΔH (the change in enthalpy) is positive, it means that the reaction is endothermic, absorbing heat from its surroundings. This indicates that energy is being consumed rather than released during the chemical reaction.


When a reaction is endothermic what usually happens to the temperature overtime?

The temperature will decrease. Endothermic reactions absorb heat engery, so the temperature of the suroundings will drop.


What happens to heat during an endothermic reaction?

During an endothermic reaction, heat is absorbed from the surroundings in order to break chemical bonds and allow the reaction to proceed. This absorption of heat causes the surroundings to cool down as energy is taken in by the reacting molecules.


What happens to the reaction 2NO2 N2O4 57.2 kJ when the temperature of the reaction is increased?

This is an endothermic equilibrium reaction Thus, increase temperature will push the reaction to the right. So more N2O4 is produced


What happens to energy in an endothermic reaction?

An endothermic reaction is a reaction which requires energy. The enegry is required for the reaction to take place, maning the energy is used up in the reaction. An example of an endothermic reaction is photosythesis.


Does the energy go from surrounding to the chemicals in an exothermic reaction?

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.


What happen if the ammonium chloride and water combined?

When Ammonium Chloride and water are combined and drop in temperature occurs because a endothermic reaction happens
