Enthalpy w/ Temp

[805383532]

How does a change in temperature affect enthalpy?

[SnehinRajkumar1L]

An increase in temperature leads to a change in enthalpy. Increasing temperature increases enthalpy, and vice versa.

[Deepika Reddy 1A]

If a reaction loses heat so that the products have less heat than the reactants, then the enthalpy is negative. If a reaction gains heat in order to occur, then the enthalpy is positive.

[Natalie Benitez 1E]

How do we tell with enthalpy that a reaction is exothermic or endothermic?

[Shrayes Raman]

Enthalpy is listed as h as with other examples if it is negative it is exothermic and vice versa

[Justin Quan 4I]

How do we tell with enthalpy that a reaction is exothermic or endothermic?

If enthalpy is negative, then heat is lost or released from the system and the reaction is exothermic. If enthalpy is positive, then heat is absorbed or gained into the system and the reaction is endothermic.

[Ashley Fang 2G]

It makes sense that as temperature increases, so does enthalpy if we refer back to the equation:
delta G = delta H - T(delta S)
