Solution

The correct option is A $\frac{13}{2}$
The process of heating a substance in the presence of sufficient air/ $O_{2}$ .
The substance is completely oxidised to $C O_{2} a n d H_{2} O$ accompanied by evolution of a large amount of heat.
combustion reaction of ethane is given by
$C_{4} H_{10} + \frac{13}{2} O_{2} \to 4 C O_{2} + 5 H_{2} O + Δ$
