Answer the following questions based on your study of CRE:

Design Parameter$/$Situation :

$Q1$ :

For the following parallel reactions

A $-$R $-ra=$K$\_\{1\}$ CA Main reaction

$A-S-ra=$ K$\_\{2\}*$ C$\_\{$A$\}^2$ Side reaction

Mention how to maximize the main reaction and minimize the side reaction If the activation energy E$1=79$ kJ$/$mol$,$ E$2=113$ kJ$/$mol Mention the effect of temperature in maximizing the main reaction.

$Q2$:

The maximum allowable temperature for a reactor is $800$ K$.$ At present, our operating set point is $780$ K$,$ the $20-$K margin of safety to account for fluctuating feed, sluggish controls. etc. Now, with a more sophisticated control system we would be able to raise our set point to $792$ K with the same margin of safety that we now have. By how much can the reaction rate, hence, production rate, be raised by this change if the reaction taking place in the reactor has activation energy of $175$ kJ$/$mol$?$

$Q3$:

In a process industry, you are a process engineer operating PFR that handles an exothermic gas reaction.

N $2+3$H $2<--2$NH$3$

Suddenly, there is increase in the temperature, what action you will do to avoid any accidents $?$
