Question

In which of the following reactions the entropy change is positive?

$H_{2} + \frac{1}{2} O_{2} \to H_{2} O$
$\underset{(g)}{{N a}^{+}} + \underset{(g)}{{C l}^{-}} \to \underset{(s)}{N a C l}$
$\underset{(1)}{N a C l} \to \underset{(s)}{N a C l}$
$\underset{(l)}{H_{2} O} \to \underset{(g)}{H_{2} O}$

The correct answer is: $stack H subscript 2 end subscript O with left parenthesis l right parenthesis below rightwards arrow stack H subscript 2 end subscript O with left parenthesis g right parenthesis below$
