The decomposition reaction X ( g ) 3 Y ( g ) is studied at constant volume and temperature. For pure X ( g ) as the starting material, the first few readings of the observed total pressure P as a function of time are given below: array |l|c|c|c|c| Time (min) & 0 & 1 & 2 & 4 Total Pressure P(atm) & 8 & 16 & 20 & P ₁ array The correct statement(s), assuming ideal gas behaviour, is/are:

Options

  1. AP ₁ is 23 atm.
  2. BThe total pressure, on completion of reaction, will be 24 atm .
  3. CThe partial pressure of Y will exceed that of X in less than 1 min.
  4. DThe partial pressures of X and Y will be equal when the total pressure is 12 atm.

Correct answer

D. The partial pressures of X and Y will be equal when the total pressure is 12 atm.
