When `100 ml` sample of methane and ethane along with excess of `O_(2)` is subjected to electric spark, the contraction in volume was observed to be `212 ml`. When the resulting gases were passed through `KOH` solution, further contraction in volume wasA. `60 ml`B. `96 ml`C. `108 ml`D. `124 ml`

When `100 ml` sample of methane and ethane along with excess of `O_(2)

1.	When `100 ml` sample of methane and ethane along with excess of `O_(2)` is subjected to electric spark, the contraction in volume was observed to be `212 ml`. When the resulting gases were passed through `KOH` solution, further contraction in volume wasA. `60 ml`B. `96 ml`C. `108 ml`D. `124 ml`
Answer» Correct Answer - D `{:(CH_(4)(g),+,2O_(2)(g),rarr,CO_(2)(g),+,2H_(2)O(l)),(x,,2x,,x,,):}` `C_(2)H_(6)(g)+(7)/(2)O_(2)(g)rarr2CO_(2)(g)+3H_(2)O(l)` `(100-x)(7)/(2)(100-x) 2(100-x)` Total contraction in volume `2x+2.5 (100-x)= 212` `2x-2.5x= 212-250` `x=38xx2= 76` Therefore, contraction in volume when passed through `KOH` solution `=` Volume of `CO_(2)` evolved `x+2(100-x)= 124ml`

The gases obey the different gas laws only theoretically. Practically all of them show some deviation from these laws. These are called real gases. The deviation are maximum under high pressyre and at low temperature. These are comparatively small when the conditions are reversed. It has been found that the easily liquefiable gases show more deviations from the ideal gas beheviour as compared to the gases which are liqufied with diffculty. Gas deviates from ideal gas beheviour because moleculesA. are coloulessB. attract each otherC. contain covalent bondD. show Brownian Movement.
