Problem $89$

Carbon monoxide gas at $50C$ is fed to a reactor $($furnace$)$ at a rate of $100mo\frac{l}{s}.$ The

furnace is also fed with $25\%$ excess air at $40C.$ The molar composition of air can be

assumed to be $20\%$ oxygen and $80\%$ nitrogen. Carbon monoxide reacts with oxygen to

form carbon dioxide. The fractional conversion of carbon monoxide is $40\%.$ The reactor

operates adiabatically. Find the temperature at which the reactor operates.
