What is the sign of the enthalpy change for an endothermic reaction?
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
What is the impact of a change in temperature on the delta S of surroundings in a chemical reaction?
A change in temperature can affect the entropy change (delta S) of the surroundings in a chemical reaction. When the temperature increases, the surroundings absorb more heat energy, leading to an increase in entropy. Conversely, a decrease in temperature results in a decrease in entropy of the surroundings.
What is a endothermic change?
An endothermic change is a chemical reaction or physical process that absorbs heat from its surroundings. This causes the surroundings to cool down as energy is taken in to drive the reaction or process. Examples include melting ice and photosynthesis.
What can be said about an exothermic reaction with a negative entropy change?
An exothermic reaction with a negative entropy change indicates that the reaction releases heat to its surroundings and results in a decrease in disorder or randomness of the system.
Is a positive enthalpy endothermic?
Yes, a positive enthalpy change indicates that a reaction is endothermic, meaning it absorbs heat from its surroundings.
What is a endothermic?
An endothermic reaction is a chemical reaction that absorbs heat from its surroundings. change in H> 0.(6.6)

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.
What is the sign for Energy change of an endothermic reaction?
The products of the reaction will have less energy than the reactants
What happens to the temperature during an endothermic reaction?
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.
Is a positive enthalpy endothermic?
Yes, a positive enthalpy change indicates that a reaction is endothermic, meaning it absorbs heat from its surroundings.
What is the sign of ΔT in an endothermic reaction?
ΔH is the enthalpy of the reaction and will be positive in an endothermic reaction and negative in an exothermic reaction.ΔT designates a change in temperature. T2-T1 = ΔTOften the change in temperature will be negative for an endothermic reaction.
What is the difference of the endothermic and exothermic change?
An endothermic change requires heat, and an exothermic change releases heat.
How can you determine whether an equation is endothermic or exothermic?
To determine if an equation is endothermic or exothermic, you can look at the overall energy change. If the reaction absorbs energy from the surroundings, it is endothermic. If the reaction releases energy into the surroundings, it is exothermic. This can be determined by comparing the energy of the reactants to the energy of the products.
