The Changes in internal energy (∆U) for an isolated system is zero
So,
it does not exchange any energy in any form with the surroundings.
But , The entropy tends to increase in case of spontaneous reaction.
•°• , ∆S > 0 or positive.

ANSWER :
Δ S > 0
Δ S will be positive .
Details :
We know that :
Δ S = p∆V /T
T Δ S = p Δ V
p Δ V is more than 0 .
Hence the Δ S has to be positive.
.
Logical :
Δ S has to be positive because the entrophy increases from reactant to product.
This justifies the answer !
