One mole of

\mathrm{N}_2

and 3 moles of

\mathrm{H}_2

are taken in a container of capacity 8.21 lit. at

300 \mathrm{~K}

to produce

\mathrm{NH}_3.

Find the partial pressures of

\mathrm{N}_2

and

\mathrm{H}_2

if partial pressure of

\mathrm{NH}_3

after sufficient time was found to be

3 \mathrm{~atm}

View answer and explanation

Correct option: A

1.5 \mathrm{~atm}; 4.5 \mathrm{~atm}

Option A (

1.5 \mathrm{~atm}; 4.5 \mathrm{~atm}

) is correct because it reflects the partial pressures of N2 and H2 after accounting for the consumption of reactants to form NH3.
