The plots of intensity of radiation versus wavelength of three black bodies at temperatures `T_(1),T_(2)andT_(3)` are shown . Then

A

A)`T_(3)gtT_(2)gtT_(1)`

B

B)`T_(1)gtT_(2)gtT_(3)`

C

C)`T_(2)gtT_(3)gtT_(1)`

D

D)`T_(1)gtT_(3)gtT_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
According to Wien .s law
`lambda_(m)prop(1)/(T)`
and from the figure
`(lambda_(m))_(1)lt(lambda_(m))_(3)lt(lambda_(m))_(2)`
Therefore , `T_(1)gtT_(3)gtT_(2)`

In Haber's process, ammonia is manufactured according to the following reaction N_(2(g)) + 3H_(2(g)) hArr 2NH_(3(g)) , Delta H^(@) = -2.4 kJ The pressure inside the chamber is maintained at 200 atm and temperature at 500^(@)C . Generally this reaction is carried out in presence of Fe catalyst. The preparation of ammonia by Haber's process is an exothermic reaction. If the preparation follows the following temperature pressure relationship for its % yield. Then for temperature T_(1), T_(2) and T_(3) , the correct option is :

I, II and III are three isotherms, respectively, at T_(1) ,T_(2) , and T_(3) . Temperature will be in order.
