GATE XE (Engineering Sciences) 2024 - Question 74

Section: Thermodynamics | Type: NAT | Marks: 1

A rigid tank, initially at 1⁡bar and⁡300⁡K, contains 5⁡moles of 𝑂2, 4⁡moles of 𝑁2 , and 3⁡moles of 𝐻2 . From this tank, 2⁡moles of 𝑂2 are removed keeping the temperature constant. Assuming ideal gas behaviour, the final partial pressure of 𝑂2 (in bar) inside the tank is _______ (rounded off to three decimal places). Use 𝑅⁡ = ⁡8.314⁡J/mol.K Molecular weights of 𝐻2, 𝑁2 and 𝑂2 are 2⁡g/mol, 28⁡g/mol, and 32⁡g/mol respectively.

Answer: 0.249 to 0.251
