Q. On combustion of 4 g of the methane, 10.46 kJ of heat is liberated. Heat of combustion of methane is
A) 83.68 kJ
B) 10.46 kJ
C) 41.84 kJ
D) 20.93 kJ
Explanation
(c)
$\because$ Amount of heat evolved on combustion of 4 g of methane=10.46 kJ
$\therefore$ The amount of heat evolved on combustion of one mole of methane ($ie$, 16 g of $CH_{4}$)
$= \frac{10.46}{4} \times 16 = 41.84$kJ
