Question

how many hydrogen does 2NH3 contains?
​

Answer 1

Answer:

CHEMISTRY

N2+3H2⇌2NH3. Starting with one mole of nitrogen and 3moles of hydrogen, at equilibrium 50% of each had reacted. If the equilibrium pressure is P, the partial pressure of hydrogen at equilibrium would be:

A .

P/2

B .

P/3

C .

P/4

D .

P/6

ANSWER

Initial mole ratio N2:H2 is 1:3

At equilibrium, 50% of N2, H2 has reacted and equilibrium pressure is P

N2+3H2→2NH3y3y2y

At equilibrium, 50% of each reactant reacted, the number of moles will become half.

The mole of N2=y−2y

The moles of H2=3y−23y

THE moles of NH3=22y

Total moles at equilibrium=2y+23y+22y=3y

Partial pressure of H2=TotalmolesMolesofH2×Totalpressure=23y×3y1×
