The atmosphere of the planet Venus is almost entirely composed of carbon dioxide (about 96.5% CO2). The carbon dioxide on Venus could be in equilibrium with carbonate ions in minerals on the planet's crust. Two possible equilibrium systems involve CaSiO3 and MgSiO3. CaSiO3(s) + CO2(g) ⇔⇔CaCO3(s) + SiO2(s). System 1 MgSiO3(s) + CaCO3(s) + SiO2(s) ⇔⇔ CaMgSi2O6(s) + CO2(g) System 2 The first graph that follows shows the expected pressures of carbon dioxide (in atm) at different temperatures for each of these equilibrium systems. (Note that both axes on this graph are logarithmic). The second graph is a phase diagram for carbon dioxide. Examine the graphs and answer the question Q#1: The partial pressure of carbon dioxide on the surface of Venus is 91 atm. What is the value of the equilibrium constant (Kp) if the Venusian carbon dioxide is in equilibrium according to system 1? According to system 2?
