For the reaction $$PCl_{5}(g) \rightleftharpoons PCl_{3}(g)+Cl_{2}(g)$$, the forward reaction at constant temperature is favoured by: 

The solubility of $$AgI$$ in $$NaI$$ solution is less than that in pure water because

The exothermic formation of $$ ClF_{3}$$ is represented by the equation: $$\displaystyle Cl_{2}(g)+3F_{2}(g)\rightleftharpoons 2ClF_{3}(g), \Delta H=-329$$ kJ
Which of the following will increase the quantity of $$ClF_{3}$$ in an equilibrium mixture of $$Cl_{2},F_{2}$$ and $$ClF_{3}$$?

(Given that $$K_a = 10^{-4}$$)

What is the effect of the reduction of the volume of the system for the following equilibrium?

The value of the ion product constant for water, $$(K_w)$$ at $$60^{\small\circ}C$$ is $$9.6\times10^{-14}\, M^2$$. What is the $$[H_3O^+]$$ of a neutral aqueous solution at $$60^{\small\circ}C$$ and the nature of an aqueous solution with a $$pH = 7.0$$ at $$60^{\small\circ}C$$ are respectively?

Following two equilibrium is simultaneously established in a container: $$\displaystyle PCl_{5}(g)\rightleftharpoons PCl_{3}(g)+ Cl_{2}(g)$$ and  $$CO(g)+ Cl_{2}(g) \rightleftharpoons COCl_{2}(g)$$
If some Ni(s) is introduced in the container forming $$Ni(CO)_{4}$$(g), then at new equilibrium:

If first dissociation of $$X(OH)_3$$ is $$100\mbox{%}$$ whereas second dissociation is $$50\mbox{%}$$ and third dissociation is negligible then the $$pH$$ of $$4\times10^{-3}\space M\space X(OH)_3$$ is :
