Diamond is harder than graphite .

Explain, why diamond is very hard but graphite is soft .

Assertion (A) : Graphite is chemically more reactive than diamond . Reason (R) : Diamond is very hard but fraphite si soof .

How many of the following parameters/properties are greater for diamond as compared to graphite ? Denisty, Electrical resistivity, Thermal conductivity, stability,

Diamonds are formed from graphite under high pressure in coal mines. Calculate the equilibrium pressure (in atm) at which graphite is converted to diamonds at 25^(@)C (assumed constant) given densities of rho_("graphite")=2g//c c & rho_("diamond")=3g//c c .(DeltaG_(f)^(@)) for diamonds is "3 k J mol"^(-1) from graphite

Assertion :- (A) Graphite is good conductor of electricity however diamond belongs to the category of insulators . Rason (R ) Grapite is soft in anture on the hand diamond is very hard and brittle.

Diamond and graphite are ………………..,

A : C_("diamond") rightarrow C_("graphite") Delta H and Delta U are same for this reaction. R: Entropy increases during the conversion of diamond to graphite.

Assertion : Among the carbon allotropes, diamond is an insulater, wherea, graphite is a good conductor of electricity. Reason : Hybridization of carbon in diamond and graphite are sp^3 and sp^2 , respectively.
