MCQ - 285-2471

Question:

1 mole of N2 and 4 mole H2 are taken is 15L flask at 27C0. After complete conversion on of N2 into NH3, 5L of H2O added. Pressure set up in the flask is

  1. 3×0.0821×30015 atm
  2. 2×0.0821×30015 atm
  3. 1×0.0821×30015 atm
  4. 2×0.0821×30015 atm

Correct Answer: D

Explanation:

Since the volume of the gas is equal to the volume of container, volume will be 15-5=10, b/c after completion of reaction 5 ml volume is reduced that ‘why this space is occupied by water. According to balance chemical equation, three moles of hydrogen react with I mole of nitrogen so, the n=1 mole left behind after the reaction. N23H22NH3 1 : 3 P=1×0.0821×30010 atm
