Calculate ΔHo (in kJ) for each reaction and indicate whether each reaction is exothermic or endothermic by nature. Find the rest of the standard enthalpies of formation, (ΔH0f ) that you will need yourself in the literature. [5 marks]
(Gegee: / Given: ΔH0f for CH3CO2Na(aq) = - 726.1 kJ/mol)
a) CH3CO2H (l) + NaHCO3 (s) →CH3CO2Na (aq) + CO2 (g) + H2O (l)
b) 2 CH3CO2H (l) + Na2CO3 (s) → 2 CH3CO2Na (aq) + CO2 (g) + H2O (l)
