Which of the following equations correctly represents the standard heat of formation $(\Delta H_f^o)$ of methane

A
$C$(diamond) $ + 4{H_{(g)}} \to C{H_{4\,(g)}}$
B
$C$ (diamond) $ + 2{H_{2\,(g)}} \to C{H_{4\,(g)}}$
✓
$C$ (graphite) $ + 2{H_{2\,(g)}} \to C{H_{4\,(g)}}$
D
$C$ (graphite) $ + 4{H_{(g)}} \to C{H_{4\,(g)\,}}$

✓

Answer

Correct option: C.

$C$ (graphite) $ + 2{H_{2\,(g)}} \to C{H_{4\,(g)}}$

(c)${C_{(graphite)}} + 2{H_2}(g) \to C{H_4}(g)$
