Question

A chemist knows that the $\Delta H^o = -485$ kJ for the reaction 2H₂_(g) + O_2
(g) ---> 2H₂O _(g) ,and that

$\Delta H^o = -537$ kJ for the reaction H_{2 (g)} + F_{2 (g)} ---> 2HF _(g).

With this information he calculated the $\Delta H^o$ for the reaction 2H₂O _(g) + 2F₂ _(g) ---> 4HF_(g) + O_{2 (g)} and predicted whether $\Delta S^o$ was positive or negative. How?
