Chemistry Theory and MCQ'S

[mawak]

I opened this thread for the upcoming chemistry paper...........any general discussion regarding chemistry or any usefull stuff you want people to know could be posted here........for starting the thread let me tell you something which has been frequently asked........Haber and Contact process


Haber Process.
Catalyst = Iron
Raw Materials = Hydrogen and Nitrogen
Temperature = 450 C
Pressure = 200 ATM


Contact Process
Catalyst = Vanadium 5 Oxide
Temperature = 450 C
Pressure = 2-3 ATM
Raw Materials = Sulphur,Air,Water

Hope it comes in handy

Umm but in the Contact process isn't the temperature 200C???????

Nope..........The temperature remains the same in both the processes.(Confirmed by the book) :mrgreen:

Does anybody know what boyle's law is? :ugeek:

 

[Angraiz]

It states that, within a closed system, the pressure is inversely proportional to the volume of a gas, provided the temperature remains constant.

So if the pressure is 1 atm pressure and the volume is 20 cm cube, and if the pressure is doubled, the volume will become 10 cm cube. Provided temperature for both readings is same.
