Using Hess's law, determine the enthalpy for the reaction of Pb(s)+C(s)+3/2O2?(g)?PbCO3?(s) given the following data (2pt) : Pb(s)+21?O2?(g)?PbO(s)C(s)+O2?(g)?CO2?(g)PbCO3?(s)?PbO(s)+CO2?(g)??Hrxn?=?219kJ?Hrxn?=?394kJ?Hrxn?=86kJ? Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: ×10 Answer units
To determine the enthalpy of the reaction of interest, we can use Hess's lawIt states that the enthalpy change of a reaction is the same whether it occurs in one step or a series of steps. We can use the given reactions and their enthalpy changes to construct the desired reaction and determine its enthalpy change.
