Please calculate the standard reaction entropy 4,S°(JK-1mol-1), the standard reaction enthalpy Hº(kJmol-1), the standard reaction Gibbs
energy 4,Gº(kJmol-1), and the maximum nonexpansion work that can be gained from the oxidation of HCI (g) at 298.15K.
Instruction: Please enter all answers with two decimal places, for example: -344.101 is written as -344.10, please pay attention to the units,
particularly As in J/(K.mol) while others is kJ/mol
(1) 4,5°(JK-1 mol-1) =
(2) 4,H°(kJmol-1) =
Please using your results from (1) and (2) to calculate the the standard reaction Gibbs energy:
