1 mole of

{\mathrm{N}_2}{\mathrm{O}_4}\left( \mathrm{g} \right)

at 300 K is kept in a closed container under 1 atm. It is heated to 600 K when 20% by mass of

{\mathrm{N}_2}{\mathrm{O}_4}\left( \mathrm{g} \right)

decomposes to

\mathrm{N}{\mathrm{O}_2}\left( \mathrm{g} \right)

. The resultant pressure is

View answer and explanation

Correct option: B

2.4 atm

Option B (2.4 atm) is correct because it represents the resultant pressure calculated considering the decomposition of N2O4 and the temperature change.
