Marks: +1, -0

If the standard enthalpy change (∆rH⊖) for a certain reaction at 298K and constant pressure is −1860‌kJ‌mol−1, the standard entropy change (∆syyS⊖) of the same reaction is −550JK−1mol−1, which one of the following statements is correct?

(∆ sysSθ)+∆ surSθ=−7692Jmol−1K−1, the reaction is spontaneous
(∆‌sys ‌S⊖)+∆‌surr ‌S⊖=−5692Jmol−1K−1, the reaction is non- spontaneous
(∆‌sys ‌S⊖)+∆‌surr ‌S⊖=+5692Jmol−1K−1, the reaction is spontaneous
(∆‌sys ‌Sθ)+∆‌surr ‌Sθ=+7692Jmol−1K−1, the reaction is non- spontaneous
