Stoichiometry
One mole of methane undergoes complete combustion in a stoichiometric amount of air. The reaction proceeds as CH₄ + 2O₂ → CO₂ + 2H₂O. Both the reactants and products are in gas phase. ΔH°298 = - 730 kJ/mole of methane. If the average specific heat of all the gases/vapour is 40 J/mole.K, the maximum temperature rise of the exhaust gases in °C would be approximately equal to

Stoichiometry
Pick out the wrong statement about the recycle stream in a process.

Recycling in a process does not help in getting higher extent of reaction

The ratio of the quantity of a reactant present in the reactor feed of a recycling operation to the quantity of the same reactant entering the process as fresh feed is called combined feed ratio

Recycling is exemplified by refluxing back a part of the distillate to the distillation column to maintain the quantity of liquid within the column

Recycling in a process stream helps in utilising the valuable reactants to the maximum with minimum loss of reactants
