Problem

A litre of ethylene and methane gaseous mixture on complete combustion at

25^\circ\text{C}

produces 6.11 litre of

\text{CO}_2

. Find out the amount of heat evolved on burning one litre of gaseous mixture. The heats of combustion of

\text{C}_2\text{H}_4

and

\text{CH}_4

are

-1423

and

-891 \text{ kJ mol}^{-1}

25^\circ\text{C}

. (IIT 1991)
