Step 1 — Find total moles at equilibrium:

mol

Step 2 — ICE table (initial: 1 mol ,  = degree of dissociation):

| | AB₂ | A | B | Total |
|--|--|--|--|--|
| Initial | 1 | 0 | 0 | 1 |
| Equil. |  |  |  |  |

Step 3 — Mole fractions and partial pressures (P = 1.9 atm):

atm

Step 4 — :

(nearest integer , where )
