Which statement below is always true for a spontaneous chemical reaction?

Question

delta Ssys delta Ssurr = 0

delta Ssys delta Ssurr < 0

delta Ssys delta Ssurr > 0

delta Ssys – delta Ssurr = 0

delta Ssys – delta Ssurr < 0

Answer 1

2nd law of thermo

for an irreversible  reaction (spontaneous) dS universe &gt;0

therefor delta Ssys  plus delta Ssurr &gt; 0
