Equilibrium Tes...

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

When $$0.1\ mol$$ arsenic acid, $$H_{2}AsO_{4}$$ is dissolved in $$1L$$ buffer solution of $$pH = 4$$, which of the following hold good? $$K_{1} = 2.5\times 10^{-4}, K_{2} = 5\times 10^{4}, K_{3} = 2\times 10^{-23}$$ for arsenic acid $$['< <'$$ sign denotes that the higher concentration is at least $$100$$ times more than the lower one]. 

The volume of the reaction vessel containing an equilibrium mixture is increased in the following reation.
$$SO_2Cl_{2(g)} \, \rightleftharpoons \, SO_{2(g)} \, + \, Cl_{2(g)}$$.
When  equilibrium is re-established :

For the given endothermic reaction, $$A(g)\rightleftharpoons  2B(g)$$. The variation in concentration due to different changes is plotted.
Neglect the slope of change in concentration.

For a chemical reaction $$3 \left( g \right) +Y(g)\leftrightharpoons { X }_{ 3 }Y_{ (g) }$$, the amount of $${ X }_{ 3 }Y$$, at equilibrium is affected by:

The osmotic pressure of equimolar solutions of a) $$Al_2(SO_4)_3$$, b) $$KCl$$ and c) $$sugar$$ will be:

Which of the following is a true statement:

One litre of water contains $$1.0\times { 10 }^{ -7 }$$ moles of $${ H }^{ + }$$ ions. The degree of ionization of water is:

The ionization constant of benzoic acid is $$6.46 \times 10^{-5}$$ and $$K_{sp}$$ for silver benzoate is $$2.5\times 10^{-13}$$. How many times is silver benzoate more soluble in a buffer of $$pH = 3.19$$ compared to its solubility in pure water?

$$H_2(g)+I_2(g)\leftrightharpoons 2HI(g)$$
