Question

Calculate the standard enthalpy change for the reaction at C. Standard enthalpy of formation values can be found in this list of thermodynamic properties.

ΔH∘rxn = ____kJ

Answer 1

As in the previous problem use ∆Hrxn = ∑∆Hº_products - ∑∆º_Hreactants

Look up the values in the table provided and then substitute into the above formula
