If the combustion of 1g of graphite produces 20.7 kJ of heat, what will be molar enthalpy change? Give the significance of sign also.
Answers (1)
We know that, 1 mole of carbon = 12g
To calculate the molar enthalpy, change of graphite, we need to multiply enthalpy change for 1g carbon along with its molar mass. Which as per the information provided in the question can be calculated as,
(negative sign depicts exothermic reaction as there is heath involved)
