The formation of NO 2 F from NO 2 and F 2 as per the reaction 2 NO 2 g + F 2 g ⟶ 2 NO 2 F g is a second-order reaction, first order with respect to NO 2 and first order with respect to F 2 . If NO 2 and F 2 are present in a closed vessel in ratio 2 : 1 maintained at a constant temperature with an initial total pressure of 3   atm , what will be the total pressure in the vessel after the reaction is comple

Options

  1. A1   atm  
  2. B2   atm
  3. C2 . 5   atm
  4. D3   atm

Correct answer

B. 2   atm

Step-by-step solution

In a closed container at a constant temperature PV = nRT   V   &   T   constant Pressure P ∝ n (Number of moles) The initial total pressure is 3   atm and the partial pressures of NO 2   and   F 2 will be in 2 : 1 ratio.                 2 NO 2 g       +         F 2 g    →    2 NO 2 F g t = 0         2   atm           &#160
