1 What is the free energy change for the reaction SiO2s Pbs

1.) What is the free energy change for the reaction

SiO₂(s) + Pb(s) PbO₂(s) + Si(s)?

Î”G °_f (PbO₂) = -217 kJ/mol

Î”G °_f (SiO₂) = - 856 kJ/mol

step by step and explain please

free energy of PbO2- that of SiO2 = -217-(-856)

= 639 Kj/mol
