Equilibrium Tes...

For the reaction $${ I }_{ 2 }(g)+{ H }_{ 2 }(g)\rightleftharpoons 2HI(g)$$,
what is the effect on the equilibrium position when the pressure of the reaction vessel is increased?

Degree of ionisation does not depend on:

Dissociation events in $$H_2O \rightarrow H^+ +OH^-$$ is termed as ionization because :

Which of the following will not function as a buffer solution?

The state of equilibrium refers to:

How many grams of ammonium chloride should be dissolved in 500 mL of water to have a solution of pH 4.5? 

Consider the reactions,
(i) $$P{ Cl }_{ 5 }(g)\rightleftharpoons P{ Cl }_{ 3 }(g)+{ Cl }_{ 2 }(g)$$
(ii) $${ N }_{ 2 }{ O }_{ 4 }(g)\rightleftharpoons 2{ NO }_{ 2 }(g)$$
The addition of an inert gas at constant volume:

For the reaction, $$P{ Cl }_{ 5 }(g)\rightleftharpoons P{ Cl }_{ 3 }(g)+{ Cl }_{ 2 }(g)$$, the position of equilibrium can be shifted to the right by:

Densities of diamond and graphite are $$3.5$$ and $$2.3$$ $$g/mL$$ respectively. Increase in pressure on the equilibrium 
$${ C }_{ diamond }\rightleftharpoons { C }_{ graphite }$$:

For the reaction,
$$2A(g)+B(g)\rightleftharpoons 3C(g)+D(g)$$
two moles each of $$A$$ and $$B$$ were taken into a flask. The following must always be true when the system attained equilibrium:
