Can anyone help me pleeeease!!
Calculate the enthalpy change for thermal decomposition of lithium carbonate (li2c03) given enthalpy of formation for li2c03- -1216 kj mol-1, li02- -598 kj mol-1 and c02- -394 kj mol-1. I got 224 kj mol-1, but I don't think it's right.
Calculate the enthalpy change for the reaction; c(graphite)>> c(diamond)
Enthalpy of combustion of carbon- graphite is -393.5 kj mol-1 and carbon-diamond is -395.4 kj mol-1.
