A one litre flask is full of brown bromine vapour. The intensity of brown colour of vapour will not decreases appreciably on adding to the flask some

A

pieces of marble

B

animal charcoal powder

C

carbon tetrachloride

D

carbonisulphide

Text Solution

Verified by Experts

The correct Answer is:
A
Marble `(CaCO_(3))` do not react, adsorb, absorb, or dissolve `Br_(2)`.As such there is no change is colour of `Br_(2)`. Remaining dissolves or absorb or adsorb bromine.

At room temperature following traction goes to completion 2AB(g)+B_(2)(g)rarr2AB_(2)(s) AB_(2) is solid with negligble vapour pressure below 0^(@)C . At 300 K, the AB in the smaller flask exerts a pressure of 3 atm and in the larger flask B_(2) exerts a pressure of 1 atm at 400 K when they are separated out by a close valve, The gases are mixed by opening the stop cock and after the end of the reaction the flask are cooled to 250 K The final pressure is :

When 2g of a gas A is introduced into an evacuated flask kept at 25^@C , the pressure is found to be one atmosphere. If 3 g of another gas B are then added to the same flask, the total pressure becomes 1.5 atm. Assuming ideal gas behaviour, calculate the ratio of molecular weights M_A : M_B .
