5 0

Answer:

The correct answer to the question is

The standard heat of reaction for the reaction is

a. 216.8 kJ released per mole

Explanation:

The heat of reaction is given by [Heat of formation of products] - [Heat of formation of reactants]

In the question we have, heat of formation of the products Zn+2 (aq) = -152.4 kJ/mole and the heat of formation of the reactants = 64.4 kJ/mole

Therefore, the heat of formation of the reaction = (-152-64.4) kJ/mole or

-216.8 kJ/mole released
