At what temperature will most probable speed of the molecules of the second member of homologous series `C_(n)H_(2n-2)` be the same as that of `SO_(2)` at `527^(@)C`.

Options

A. 259.4 K
B. 400 K
C. 532.4 K
D. None of these

Answer

c

Explanation

(c) Second member of `C_(n)H_(2n)` series
`=C_(3)H_(6)=42`
`=sqrt((8RT_(1))/(piM_(1)))=sqrt((8RT_(2))/(piM_(2)))=(900)/(71)=(T_(2))/(42)`
`T_(2)=532.4K`
