A system that changes spontaneously without an enthalpy change select one:
a. is impossible.
b. becomes more disordered.
c. becomes more ordered.
d. releases heat.

Respuesta :

I believe a system that changes spontaneously without an enthalpy change becomes more disordered. Spontaneous reactions are driven by decreasing enthalpy and increasing enthalpy. A sponataneous reaction occurs without being driven by some outside force. Chemical reacrions are driven by two driving forces, namely, the enthalpy and the entropy.
