Question

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?

Answer 1

Step-by-step explanation:

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

Hence, relation between spontaneity and entropy is as follows.

`Delta G = \Delta H - T \Delta S`

= +ve - (+ve. +ve)

= +ve - ve

= -ve

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

Answer 2

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