A volume of \( 4.0 \mathrm{~L} \) of a mixture of ethane and methane gases on complete combustion at \( 300 \mathrm{~K} \) produced \( 6.0 \mathrm{~L} \) of carbon dioxide. Find out the amount of
P heat evolved on burning 1 L of gaseous mixture. The heats of combustion of ethylene and methane are
W -1573 and \( -890 \mathrm{~kJ} \) per mole, respectively, at \( 300 \mathrm{~K} \).
(a) \( 4926 \mathrm{~kJ} \)
(b) \( 50 \mathrm{k} \mathbf{J} \)
(c) \( 1231.5 \mathrm{~kJ} \)
(d) \( 200 \mathrm{k} J \)
