Q. Consider following pairs of gases $A$ and $B$ [table] S. no. | $\mathbf{A}$ | $\mathbf{B}$ ; (i) | $CO_{2}$ | $N_{2}O$ ; (ii) | $CO$ | $N_{2}$ ; (iii) | $O_{2}$ | $O_{3}$ ; (iv) | $H_{2}O$ | $D_{2}O$ ; (v) | $\ ^{235}UF_{6}$ | $\ ^{238}UF_{6}$ [/table] Relative rates of effusion of gases $A$ and $B$ is in the order
A) $a = b < c < d < e$
B) $a = b < d < c < e$
C) (i)= (ii) < (v) < (iv) < (iii)
D) $a < b < c < d < e$
Explanation
The correct answer is Option C: (i)= (ii) < (v) < (iv) < (iii).
