When heated, magnesium carbonate spontaneously decomposes to magnesium oxide and carbon dioxide:MgCO3(s) → MgO (s) + CO2(g). ΔG ̊ = ? A sample of solid MgCO3was placed in a sealed jarand was heated to 500 ̊C until the system reachedequilibrium. The pressure of CO2at equilibrium was found to be 1.43 atm.Determine the value of ΔG ̊ for the reaction at 500 ̊C. (a)–2.30kJ/mol (b)–1.49kJ/mol (c)–0.40 kJ/mol (d)0.23 kJ/mol (e)1.59 kJ/mol
