Given Data:
- Mass of N2 = 28gm
- Mass of O2 = 32gm
- Temperature (T) = 1800 K
- Initial pressure = 2 atm
- % dissociation of N2 = 30%
- % dissociation of O2 = 50%
Calculations:
Step 1: Finding moles of N2 and O2
- Moles of N2 = 28gm / 28gm/mol = 1 mol
- Moles of O2 = 32gm / 32gm/mol = 1 mol
Step 2: Finding moles of dissociated N2 and O2
- Moles of dissociated N2 = 30% of 1 mol = 0.3 mol
- Moles of dissociated O2 = 50% of 1 mol = 0.5 mol
Step 3: Finding total moles of N2 and O2 after dissociation
- Total moles of N2 = 1 mol - 0.3 mol = 0.7 mol
- Total moles of O2 = 1 mol - 0.5 mol = 0.5 mol
Step 4: Finding total moles of gas after dissociation
- Total moles of gas = 0.7 mol (N2) + 0.5 mol (O2) = 1.2 mol
Step 5: Applying ideal gas equation
- PV = nRT
- (2 atm) V = (1.2 mol) (0.0821 L.atm/mol.K) (1800 K)
- V = 0.1 L
Step 6: Finding pressure after dissociation
- P' = (nRT) / V
- P' = (1.2 mol) (0.0821 L.atm/mol.K) (1800 K) / 0.1 L
- P' = 2.8 atm
Therefore, the pressure in the vessel after the dissociation of N2 by 30% and O2 by 50% is 2.8 atm. Hence, the correct answer is (3) 2.8 atm.
