Q 1: The heat of combustion of methane, carbon monoxide, and hydrogen are P, Q, and R respectively. For the reaction below,

{\mathrm{CH}}_4+H_2O\rightarrow\mathrm{CO}+3H_2

The heat of the reaction is given by





Ans is A)

Explanation:

Q 2: Formaldehyde is produced by the oxidation of methane in a reactor. The following two parallel reactions occur.

{\mathrm{CH}}_4+O_2\rightarrow\mathrm{HCHO}+H_2O {\mathrm{CH}}_4+{2O}_2\rightarrow{\mathrm{CO}}_2+2H_2O

Methane and oxygen are fed to the reactor. The product gases leaving the reactor include methane oxygen, formaldehyde, carbon dioxide, and water vapor. 60 mol/s of methane enters the reactor. The molar flow rate (in mol/s) of CH4, O2, and CO2 leaving the reactor are 26, 2, and 4 respectively. The molar flow rate of oxygen entering the reactor is ______________  mol/s.

Ans is 40 mol/s)
