Answer:
"Both signs are possible" is the correct choice.
Explanation:
- The indication including its change in enthalpy depends on the concentration.
- As when the enthalpy seems to be negative besides purposeful unexpected temperatures lower, as well as successful for necessary response at extremely high temperatures.
As such that when both signals could have been the enthalpy change.
If the dissolution of borax in water is spontaneous, so the change in enthalpy should be negative.
What is enthalpy?
Enthalpy of the reaction tells about the total amount of energy released or absorbed during any chemical reaction.
And for the spontaneous reaction, value of standard Gibb's free energy change of the reaction should be negative and formula will be represented as:
ΔG = ΔH - TΔS, where
ΔH = change in enthalpy
For the spontaneous reaction, value of enthalpy should be negative so that we get the negative value of ΔG.
Hence change in enthalpy should be negative.
