In the manufacture of benzaldehyde in an experimental reactor, a mixture of toluene and air is passed through a catalyst bed where it reacts to form benzaldehyde:
C6H5CH3 + O2 −→ C6H5CHO + H2O

Dry air and toluene gas are fed to the reactor at a temperature of 175 ◦C and at atmospheric pressure.

To maintain a high yield air is supplied in 100 per cent excess over that required for complete conversion
of the toluene charged. The toluene feed rate is 1.2 kmol hr−1. 13% of the toluene charge is converted to benzaldehyde and 0.5% burns to form CO2 and H2O:
C6H5CH3 + 9O2 −→ 7CO2 + 4H2O

Cooling water is circulated through a jacket on the converter entering at 25◦C and leaving at 40 ◦C. The hot gases leave the reactor at 190◦C.

Calculate:
(a) The composition of the inlet stream to the reactor.
(b) The composition of the exhaust gas from the reactor.
(c) The flow rate of cooling water in kg hr−1
