Question

Densities of diamond and graphite are 3.5 and 2.3 g/mL.

C (diamond) C (graphite) $\Delta$ rH = – 1.9 kJ/mole

favourable conditions for formation of diamond are

A

High pressure and low temperature

B

Low pressure and high temperature

C

High pressure and high temperature

D

Low pressure and low temperature

Answer

High pressure and high temperature

Explanation

Solution

High temperature will favour backward reaction as reaction is exothermic. While on increasing pressure reaction will shift in direction higher density.
