The standard heat of reaction for the oxidation of ammonia is given below:

$4$ NH $($g$)5$ O $($g$)4$ NO$($g$)6$ H O$($v$)$: $9047$ kJ$/$mol $$

One hundred mol NH $/$s and $200$ mol O $/$s at $25$ C are fed into a reactor in which the ammonia is completely consumed. The product gas emerges at $300$ C$.$ Calculate the rate at which heat must be transferred to or from the reactor, assuming operation at approximately $1$ atm.
