1. describe why it isnecessary to monitor levels of pollutants in our atmosphere

2.what reaction conditions must be met for dynamic equilibrium to be established?

3. describe why a moderate temperature is chosen for the production of ammonia

4.explain why the monitoringofhte reaction vessel in the Haber process is important

 

[04er]

honestly, all the information can be found in text books. I'll answer one question though

3. describe why a moderate temperature is chosen for the production of ammonia

A = the direct synthesis reaction of ammonia from its gases nitrogen and hydrogen is an example of an exothermic reaction that reaches equillibrium. Because this reaction is exothermic, we should remove heat to drive the equillibrium position to the right by Le Chatelier's Principle. This however lowers the rate of reaction and makes it an impractical method. High temperatures on the other hand result in fast reaction rate but low yield of ammonia. Hence, we choose a moderate temperature so that the reaction proceeds at a moderate rate to produce a moderate yield.

we need to monitor pollutants in our atmosphere such as carbon monoxide and carbon (soot) to protect ourselves from their toxins and maintain physical and environmental well-being...as you know cabrin monixide is a poisonous gas and may kill huamsn when inahled, and carbon(soot) may also be inahlked and clog the lungs, causing difficulty in breathing. Carbon is also a black power so it can stick to the walls of city buildings/ruin the aesthetic quiality of our built envrionrment...

well basically in order for the haber process to work efficiently certain optimal conditions need to be met (temp, pressure, conc of substances, purity of gases) so the monitoring of the reaction vessel in the haber process is important as it ensures these optimal condtions are consistently met

 

[gershy]

Also because catalysts are used in the Haber process, it is important that no chemicals which "poison" the catalyst enter the reaction chamber.

 

[TheKing]

change "poison" with react?
and seriously... its pretty self explanatory in the textbooks and theres no point in you relying on others to do your homework, you learn more if u do it by yourself.

From memory

Dynamic equil:

closed envir-
Const environment

 

[mr EaZy]

Dynamic equil:
no macroscopic cahnges can be seen

forward reaction = reve. reaction

And also that stuff about K CONST = Quotient const (only for those doing industrial chemn)

 

[mr EaZy]

im sure your teachers would have explained this already.

I agree with "THEKING" :-(

quiet alot of spam..... glad u could post so many sentences in each reply....
