Two moles of `NH_(3)` when put into a previously evacuated vessel ( one litre), partially dossociate into `N_(2) and H_(2).` If at equlib rium one mole of `NH_(3)` is present, the equlibrium constant isA. `3//4 mol^(2) litre^(-2)`B. `27//64 mol^(2) litre^(-2)`C. `27//32 mol^(2) litre^(-2)`D. `27//16 mol^(2) litre^(-2)` |

Answer» Correct Answer - D `2NH_(3)hArrN_(2)+3H_(2)` `{:("Initial concentration",2,0,0),("At equlibrium concentration",1,1//2,3//2):}` `K_(c)=([N_(2)][H_(2)]^(3))/([NH_(3)]^(2))=(1//2xx[3//2]^(3))/(I^(2))=27/16` `[Given 2-2x=1,2x=1,x=1//2]` |
