Question

Among the following reactions, identify which has an entropy (∆S_{sys}) greater than zero.

Accepted Answer

2 KClO_{3}(s) → 2 KCl(s) + 3 O_{2}(g)

Answer

2 H_{2}(g) + O_{2}(g) → 2 $$H_{2}O(l)$$

Answer

2 Mg(s) + O_{2}(g) → 2 MgO(s)

Answer

3 $$Ca^{2+}(aq) + 2 PO$$_{4}^{3–}(aq) → Ca_{3}(PO_{4})_{2}(s)

Among the following reactions, identify which has an entropy (∆Ssys) greater than zero.
