Dalton's law of partial pressure: Partial pressure of gas = mole fraction of gas in gaseous mixture × Total pressure of gaseous mixture. p 1 = X 1 p p 2 = X 2 p p 3 = X 3 p Total pressure, p = p 1+ p 2+ p 3

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

$p_{i} = χ_{i} p_{i}^{0}$ , where $χ_{i} =$ mole fraction of $i^{th}$ gas in gaseous mixture $p_{i}^{0} =$ pressure of $i^{th}$ gas in pure state

$p = p_{1} + p_{2} + p_{3}$

$p = n_{1} \frac{RT}{V} + n_{2} \frac{RT}{V} + n_{3} \frac{RT}{V}$

$p_{i} = χ_{i} p$ , where $p_{j} =$ partial pressure of $i^{th}$ gas $χ_{i} =$ mole fraction of $i^{th}$ gas in gaseous mixture

Dalton's law of partial pressure :
Partial pressure of gas $=$ mole fraction of gas in gaseous mixture $\times$ Total pressure of gaseous mixture.
$p_{1} = X_{1} p$
$p_{2} = X_{2} p$
$p_{3} = X_{3} p$
Total pressure,
$p = p_{1} + p_{2} + p_{3}$

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

pi​=χi​pi0​, where χi​= mole fraction of ith gas in gaseous mixture pi0​= pressure of ith gas in pure state

p=p1​+p2​+p3​

p=n1​VRT​+n2​VRT​+n3​VRT​

pi​=χi​p, where pj​= partial pressure of ith gas χi​= mole fraction of ith gas in gaseous mixture
