Question

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

Accepted Answer

${p_i} = {\chi _i}p_i^ \circ $ where ${\chi _i} = $ mole fraction of ${i^{{\rm{th}}}}$ gas in gaseous mixture, $p_i^ \circ = $pressure of ${i^{{\rm{th}}}}$ gas in pure state

Answer

$p = {p_1} + {p_2} + {p_3}$

Answer

$p = {n_1}\frac{{RT}}{V} + {n_2}\frac{{RT}}{V} + {n_3}\frac{{RT}}{V}$

Answer

${p_i} = {\chi _i}p,$ where ${p_i} = $ partial pressure of ${i^{{\rm{th}}}}$ gas, ${\chi _i} = $ mole fraction of ${i^{th}}$ gas in gaseous mixture
