Calculate the heat of decomposition for this process at constant pressure and 25°C. (Look up the standard enthalpy of formation of the reactant and products in the table; ΔH°f(BaCO3(s)) = -1218.8 kJ/mol, ΔH°f (BaO(s)) = -558.2 kJ/mol and ΔH°f (Na2CO3(s)) = -1130.9 kJ/mol, ΔH°f (Na2O(s)) = -415.89 kJ/mol.)

Question

Calculate the heat of decomposition for this process at constant pressure and 25°C. (Look up the standard enthalpy of formation of the reactant and products in the table; ΔH°f(BaCO3(s)) = -1218.8 kJ/mol, ΔH°f (BaO(s)) = -558.2 kJ/mol and ΔH°f (Na2CO3(s)) = -1130.9 kJ/mol, ΔH°f (Na2O(s)) = -415.89 kJ/mol.)
MgCO3(s) → MgO(s) + CO2(g)
