Vmp = √(2RT/M) ⇒ Vmp propto √(T/M) For N2 , O2 , H2 √(300/28) < √(400/32) < √(300/2) Vmp textof N2 (300K) < Vmp textof O2 (400 K) < Vmp textof H2 (300 K)

Q. Points I, II and III in the following plot respectively correspond to ( $V_{m p} :$ most probable velocity)

$V_{m p} o f N_{2} (300 K); V_{m p} o f H_{2} (300 K); V_{m p} o f O_{2} (400 K)$

$V_{m p} o f H_{2} (300 K); V_{m p} o f N_{2} (300 K); V_{m p} o f O_{2} (400 K)$

$V_{m p} o f O_{2} (300 K); V_{m p} o f N_{2} (300 K); V_{m p} o f H_{2} (400 K)$

$V_{m p}$ of $N_{2} (300 K); V_{m p}$ of $O_{2} (400 K); V_{m p}$ of $H_{2} (300 K)$

$V_{m p} = \frac{2 RT}{M} \Rightarrow V_{m p} \propto \frac{T}{M}$
For $N_{2}, O_{2}, H_{2}$
$\frac{300}{28} < \frac{400}{32} < \frac{300}{2}$
$V_{m p} of N_{2} (300 K) < V_{m p} of O_{2} (400 K) < V_{m p} of H_{2} (300 K)$
