In the following reaction : `CaC_(2) (s) + 2H_(2) O (l) rarr C_(2) H_(2) (g) + Ca (OH)_(2) (s)` Suppose `16 gm CaC_(2)` reacts with 9 gm water and acetylene formed is collected in 10 litre vessel at temperature `300 K` then its pressure will be :A. `0.75` atmB. `0.5` atmC. `0.6` atmD. `0.25` atm |

Answer» Correct Answer - C `{:(,CaC_(2) (s),+,2H_(2)O (l),rarr,C_(2)H_(2) (g),+,Ca(OH)_(2) (s),),("Mole",(1)/(4) "mole",,(1)/(2)"mole",,-,,-,),(-,,,-,,(1)/(4) " mole",,(1)/(4) "mole",):}` `PV = nRT` `P = (0.25 xx 0.08 xx 300)/(10)` `P = 0.6 atm` |
