Solution

Ethanoic acid has the chemical formula $C H_{3} C O O H$ . We cannot make methane directly from Ethanoic acid.
We must first convert ethanoic acid to sodium ( $N a$ ) salt, after which we can produce methane ( $C H_{4}$ ) from it.
To begin, Acetic acid combines with sodium hydroxide ( $N a O H$ ) to produce Sodium acetate ( $C H_{3} C O O N a$ ) and water ( $H_{2} O$ ).
$\underset{E t h a n o i c a c i d}{C H_{3} C O O H (a q)} + \underset{S o d i u m h y d r o x i d e}{N a O H (s)} \to \underset{S o d i u m a c e t a t e}{C H_{3} C O O N a (s)} + \underset{W a t e r}{H_{2} O (l)}$
On distillation, the formed Sodium acetate combines with sodium hydroxide to produce Methane, and the chemical process is as follows.
$\underset{S o d i u m a c e t a t e}{C H_{3} C O O N a (s)} + \underset{S o d i u m h y d r o x i d e}{N a O H (s)} \to \underset{M e t h a n e}{C H_{4} (g)} + \underset{S o i d u m c a r b o n a t e}{N a_{2} C O_{3} (s)}$
