Hi!
I understood this topic in class, now i just don't know how to start the questions!
Please could somebody explain to me how to do the following question:
Calculate the Standard Enthalpy Change for the decomposition of Lea Nitrate:
2Pb(NO3)2 ----> 2PbO + 4NO2 + O2
Given:
Pb(NO3)2: Std Enthalpy of Formation (-452 kJ/mole)
PbO: Std Enthalpy of Formation (-217 kJ/mole)
NO2: Std Enthalpy of Formation (33kJ/mole)
I know to construct equations for everything, which i've done: and i'm familiar in using the triangle rule/idea, but how do i start?!
Thanks very much for your help, rep points are available!
Cheers.
