Q. Which one is not correct mathematical equation for Dalton's Law of partial pressure? Here p = total pressure of gaseous mixture
A) $p_i = x_i p_i^\circ$, where $x_i$ = mole fraction of $i^{th}$ gas in gaseous mixture, $p_i^\circ$ = pressure of $i^{th}$ gas in pure state
B) $p = p_1 + p_2 + p_3$
C) $p = n_1\frac{RT}{V} + n_2\frac{RT}{V} + n_3\frac{RT}{V}$
D) $p_i = x_i p$, where $p_i$ = partial pressure of $i^{th}$ gas, $x_i$ = mole fraction of $i^{th}$ gas in gaseous mixture
Explanation
[Solution] $p_i = x_i p_i^\circ$ is Raoult's law, not Dalton's law of partial pressures. Answer (1).
