For the transition `C` (diamond) `rarr C` (graphite), `Delta H = - 1.5 kJ` it follows thatA. diamond is more stable than graphiteB. graphite is more stable than diamondC. both diamond and graphite are equally stabelD. nothing can be predicted from this reaction

Answer» Correct Answer - B
Thermodynamical equation idicates that the reaction (transition) is exothermic, i.e., energy is released out when graphite is formed from diamond. Thus, graphite with lower energy content than diamond is relatively more stable.
