(a) For each of the following reactions, predict the sign of \(\Delta H^{0}\) and \(\Delta S^{0}\) without doing any calculations. (b) Based on your general chemical knowledge, predict which of these reactions will have K > 1. (c) In each case indicate whether K should increase or decrease with increasing temperature.

\(2 M g(s)+O_{2}(g) \leftrightarrow 2 M g O(s)\)\(2 K I(s) \leftrightarrow 2 K(g)+I_{2}(g)\)\(N a_{2}(g) \leftrightarrow 2 N a(g)\)\(2 \mathrm{~V}_{2} \mathrm{O}_{5}(s) \leftrightarrow 4 \mathrm{~V}(s)+5 \mathrm{O}_{2}(g)\)
