NEET Chemistry States of Matter / पदार्थ की अवस्थाएँ - गैस एवं द्रव NEET PYQ-States Of Matter

A gaseous mixture was prepared by taking equal moles of CO and \[{{N}_{2}}\]. If the total pressure of the mixture was found 1 atmosphere the partial pressure of the nitrogen \[({{N}_{2}})\] in the mixture is       [AIPMT (S) 2011]

A) 0.8 atm

B) 0.9 atm

C) 1 atm

D)      0.5 atm

Correct Answer: D

Solution :

\[\because \] \[^{n}CO{{=}^{n}}{{N}_{2}}\]

\[\therefore \] \[{{p}_{CO}}={{p}_{{{N}_{2}}}}\]

Given, \[{{p}_{CO}}+{{p}_{{{N}_{2}}}}=1\,\text{atm}\]

or \[2{{p}_{{{N}_{2}}=}}1\,\text{atm}\]

or \[{{p}_{{{N}_{2}}=}}0.5\,\,\text{atm}\]
