JEE MainChemistryThermodynamicsNumerical+4 / −1
28.0 L of CO 2_22​ is produced on complete combustion of 16.8 L gaseous mixture of ethene and methane at 25 ∘^\circ∘ C and 1 atm. Heat evolved during the combustion process is ‾\underline{\hspace{2cm}}​ kJ. Given : ΔHc (CH4)=−900 kJ mol−1ΔHc (C2H4)=−1400 kJ mol−1\mathrm{\Delta H_c~(CH_4)=-900~kJ~mol^{-1}}\mathrm{\Delta H_c~(C_2H_4)=-1400~kJ~mol^{-1}}ΔHc​ (CH4​)=−900 kJ mol−1ΔHc​ (C2​H4​)=−1400 kJ mol−1
