Solid Ammonium carbamate dissociates as: NH_(2)COONH_(4)(s)hArr2NH_(3)(g)+CO_(2)(g). In a closed vessel, solid ammonium carbonate is in equilibrium with its dissociation products. At equilibrium, ammonia is added such that the partial pressure of NH_(3) at new equilibrium now equals the original total pressure. Calculate the ratio of total pressure at new equilibrium to that of original total pressure. Also find the partial pressure of ammonia gas added.

A(s)hArr2B(g)+C(g) The above equilibrium was established by initially taking A(s) only. At equilibrium, B is removed so that its partial pressure at new equilibrium becomes 1//3^(rd) of original total preswsure. Ratio of total pressure at new equilibrium and at initial equilibrium will be :

For the equilibrium DeltaB(g) hArr A(g) +B(g) K_p is equal to four times the total pressure. Calculate the number of moles of A formed .

For the equilibrium AB(g) hArr A(g)+B(g) . K_(p) is equal to four times the total pressure. Calculate the number moles of A formed if one mol of AB is taken initially.
