Answer #1

b   FeO(s) + CO(g) - Fe(s) + CO2(g)

                                 for solid [FeO] = 1, [Fe] = 1

Kc   = [CO2]/[CO]

d   PbI2(s) ----------->Pb2 1 (aq) + 2I2(aq) it is not correct equation

PbI2(s) ------------>Pb^2+ (aq) + 2I^-(aq) it is correct equation

for solid [PbI2]   = 1

Kc   = [Pb^2+][I]^2

plz any doubt comment on the BOX. I will explain
