# finding Equilibrium pressure help please?

Consider the following reaction: PbCO3(s)⇌PbO(s)+CO2(g)

calculate the equilibrium pressure of CO2 in the system at 350 ∘C.

calculate the equilibrium pressure of CO2 in the system at 250 ∘C.

The formula ( delta G =delta H - T(deltaS)). that will give you your delta G.

then you will use the formula K=e^(-delta G)/(R)(T)

you will use the same temp, in both formula.
