Methanol is oxidized to form acetaldehyde. The feed to the reactor contains $180$ mol$/$s CH$3$OH at $300\backslash$deg C and $1$ atm pressure. The conversion of CH$3$OH in the reactor is $60\%.$ The O$2300\backslash$deg C and $1$ atm pressure is fed to the reactor $25\%$ excess. All species leaving the reactor are at $1$ atm pressure. The heat loss from from the reactor is $7000$ kW$.$ Calculate the temperature of the outlet stream leaving the reactor.
