Hess's Law, enthalpy,entropy,Gibbs free energy change Problem.

For the following unbalanaced reaction at 25°C


PbCO3(s)-->PbO(s)+CO2(g)


Calculate the standard enthalpy change, change in H° for the reaction


Ccalculate the standard entropy change, change in S° for the reaction.


Using the answers from above calculate the standard Gibbs free energy change, change in G° for the reaction.


Is the reaction spontaneous or not at standard conditions
