Ammonium carbamate when heated to `200^(@) C ` gives a mixture of `NH_(3) and CO_(2)` vapours with a density of `16*0` . What is the degree of disociation of ammonium carbamate ?A. `3//2`B. `1//2`C. 2D. 1 |
Answer» Correct Answer - D `{: (,NH_(2)COONH_(4),to,2NH_(3),+,CO_(2)), ("Intial" ,1"mole",,,,), ("After disso.",1-alpha,,2alpha,,alpha ),(,,,,,"Total"=1+2 alpha):}` Theoretical density `(D) propto 1/V ` Observed density ` (d) propto 1/((1+2alpha)V)` ` :. D/d = 1+ 2 alpha ` or ` alpha = 1/2 ((D-d)/d) = 1/2 ((48-16*0)/16*0) = 1*0 ` |
