Q60 · Chemistry

Which one is not correct mathematical equation for Dalton's Law of partial pressure ? Here p = total pressure of gaseous mixture

  1. 1pi=xipi∘p_i = x_i p_i^{\circ}, where xix_i = mole fraction of ithi^{th} gas in gaseous mixture, pi∘p_i^{\circ} = pressure of ithi^{th} gas in pure stateOfficial answer
  2. 2p=p1+p2+p3p = p_1 + p_2 + p_3
  3. 3p=n1RTV+n2RTV+n3RTVp = n_1\frac{RT}{V} + n_2\frac{RT}{V} + n_3\frac{RT}{V}
  4. 4pi=xipp_i = x_i p, where pip_i = partial pressure of ithi^{th} gas, xix_i = mole fraction of ithi^{th} gas in gaseous mixture
