Answer : The heat of reaction for the process is, 1374.7 kJ
Explanation :
According to Hess’s law of constant heat summation, the heat absorbed or evolved in a given chemical equation is the same whether the process occurs in one step or several steps.
According to this law, the chemical equation can be treated as ordinary algebraic expression and can be added or subtracted to yield the required equation. That means the enthalpy change of the overall reaction is the sum of the enthalpy changes of the intermediate reactions.
The main chemical reaction is,

The intermediate balanced chemical reaction will be,
(1)

(2)

(3)

We reversing reaction 1, 3 and multiplying reaction 2 by 2 and then adding all the equations, we get :
(1)

(2)

(3)

The expression for heat of reaction for the process is:



Therefore, the heat of reaction for the process is, 1374.7 kJ
Answer:
Beyond the centre of curvature
Explanation:
Atoms combine as the electrons from each atom are attracted to the nuclei of the atoms. The results in bonds ranging from 100%covalent to bonds with higher character. The combination of atoms to form compounds occurs when the compounds being formed are at lower energy than the original atoms. In chemical change, the molecules in the reactants interact to form new substances.
