Question

A mixture of propane and benzene is burnt completely in excess of oxygen at 11 0 ∘ C . It results in the production of equal volumes of CO 2 ​ ( g ) and steam (measured under identical pressure and temperature). Which of the following is correct regarding the original mixture?

C 3 ​ H 8 ​ + 5 O 2 ​ → 3 C O 2 ​ + 4 H 2 ​ O ( g ) x mole 3x mole 4x mole C 6 ​ H 6 ​ + 2 15 ​ O 2 ​ → 6 C O 2 ​ + 3 H 2 ​ O ( g ) y mole 6y mole 3y mole From the question, 3 x + 6 y = 4 x + 3 y . This simplifies to x : y = 3 : 1 . Also, the ratio of carbon to hydrogen atoms is given by n C ​ : n H ​ = ( 3 x + 6 y ) : ( 8 x + 6 y ) = 1 : 2 .
