WebDetailed Solution for Test: Thermochemistry - Question 6. ∆H given in the question is for one mole of C (g). If 6 gm of diamond and graphite are burnt in oxygen then the C (diamond) will first convert to graphite and then it will form CO 2.While C (graphite) will directly form CO 2.So due to the conversion of diamond into graphite, we will get extra heat.
