Calculate the Gibbs free energy change at 298 K for the reaction of hydrogen gas (H2) and chlorine gas (Cl2) to form hydrogen chloride gas (2HCl), given the following thermodynamic data:∆H°f (HCl) = -92.31 kJ/mol∆H°f (H2) = 0 kJ/mol∆H°f (Cl2) = 0 kJ/mol∆S°f (HCl) = -181.6 J/(mol*K)∆S°f (H2) = 130.7 J/(mol*K)∆S°f (Cl2) = 223.1 J/(mol*K)Also, determine whether the reaction is spontaneous at 298 K and if it will shift towards products or reactants.
