Question

1 out of 10 attempts Enter your answer in the provided box. Assistance Diamond and graphite are two crystalline forms of carbon. At I atm and 25 °C, diamond changes to graphite so slowly that the enthalpy change of the process must be obtained indirectly. Determine AH for Guided Solution C(diamond) Cgraphie Print with equations from the following list: c(diamaad) +02(g)CO2(g) 2CO2 (g)- 2 CO(g ) + 0,(g) (I) M/--395.4 kJ Report a F (2) M,-566.0 kJ (4) 2CO(g)- Cigraphite) + CO2(g) SH-_172 SH overall = EJ

Explanation / Answer

lets try to write the given reaction in terms of reactions 1,2,3,4

given reaction = reaction 1 - reaction 3

so,

delta H = delta H1 - delta H3

= -395.4 - (-393.5)

= -1.9 KJ

Answer: -1.9 KJ
