Solution

The correct option is C $1684 K; 2143 K$
Average speed = $\sqrt{(\frac{8 R T}{π m})}$

Most probable speed = $\sqrt{(\frac{2 R T}{m})}$

Average speed at $T_{1} K$ = MP speed at $T_{2} K f o r C O_{2}$

$\sqrt{(\frac{8 R T_{1}}{π m})} = \sqrt{(\frac{2 R T_{2}}{m})}$

$\frac{T_{1}}{T_{2}} = \frac{π}{4}$ ------(i)

Also for $C O_{2} u_{m p} = \sqrt{(\frac{2 R T}{m})} = 9 \times 10^{4}$

$= \sqrt{\frac{2 \times 8.314 \times 10^{7} \times T_{2}}{44}} = 9 \times 10^{4}$

By eq (1) We get
$T_{2} = 2143 K$
$T_{1} = 1684 K$
Hence answer is (C)
