Thermodynamically the most stable form of carbon is (a) diamond (b) graphite (c) fullerenes (d) coal

As the reaction of the type accompanied by decrease of randomness, the heat released is absorbed by the surroundings so that the entropy of the surroundings increases to such an...

[Hint : Because O3 is endothermic compound/decomposition of O3 is exothermic and ΔG is negative/decomposition of O3 is spontaneous.]

Coal is an important source of energy and hence most of the industries are located around coal mines.

(C) carbon dioxide only

According to your questions, the Correct answer is 3.

The two characteristic properties of the carbon element which leads to the formation of a very large number of organic compounds are:  Catenation Tetravalency Catenation: Carbon has the unique ability to form bonds...

(d) : Graphite has a twodimensional sheet like structure and each carbon atom makes a use of sp2 hybridisation.  The above layer structure of graphite is less compact than that of...

(b) : A more basic ligand forms stable bond with metal ion, Cl– is most basic amongst all.

(a) 1.5 × 1010 cm/sec
