Suppose an endothermic reaction has a positive change in entropy greater than the heat absorbed. What can be said about the spontaneity of this reaction?

Respuesta :

If the entropy is greater than the enthalpy, it will have more spontinaity

Explanation:

Since the given reaction is endothermic, therefore value of [tex]\Delta H[/tex] is positive. Also, it is given that value of [tex]\Delta S[/tex] is positive, that is, there will be increase in entropy.

Hence, relation between spontaneity and entropy is as follows.

              [tex]Delta G = \Delta H - T \Delta S[/tex]

                                   = +ve - (+ve. +ve)

                                   = +ve - ve

                                   = -ve

Therefore, we can conclude that there will be increase in spontaneity of the said reaction.
