Calculate the standard enthalpy change (∆H°) for the reaction of the coordination compound [Co(NH3)6]Cl3 (aq) with NaOH (aq) to produce [Co(NH3)6](OH)3 (aq) and NaCl (aq). Given, the standard enthalpy of formation (∆H°f) for [Co(NH3)6]Cl3, [Co(NH3)6](OH)3 and NaCl are -784.8 kJ/mol, -1273.6 kJ/mol and -411.2 kJ/mol, respectively.

A student needs to determine the enthalpy change of a chemical reaction using the Hess's Law equation. They have the following information:- The enthalpy change for Reaction 1 is -210 kJ/mol- The enthalpy change for Reaction 2 is -325 kJ/mol- The enthalpy change for Reaction 3 is 155 kJ/molThe student needs to use Hess's Law to calculate the enthalpy change for the following reaction:4A + 3B → 2CGiven the information above, what is the enthalpy change for the reaction?
