N2(g) + O2(g) → NO(g) ΔHrxn = +90.3 kJ NO(g) + Cl2(g) → NOCl(g) ΔHrxn = –38.6 kJ What is the value of ΔHrxn for the decompositio
Ivanshal [37]

Answer : The value of \Delta H_{rxn} is, -103.4 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 given main reaction is,

2NOCl(g)\rightarrow N_2(g)+O_2(g)+Cl_2(g)    \Delta H=?

The intermediate balanced chemical reaction will be,

(1) \frac{1}{2}N_2(g)+\frac{1}{2}O_2(g)\rightarrow NO(g)     \Delta H_1=+90.3kJ

(2) NO(g)+\frac{1}{2}Cl_2(g)\rightarrow NOCl(g)    \Delta H_2=-38.6kJ

Now reversing and multiplying by 2 of reaction 1 and 2 then adding all the equations, we get :

(1) 2NO(g)\rightarrow N_2(g)+O_2(g)     \Delta H_1=2\times (-90.3kJ)=-180.6kJ

(2) 2NOCl(g)\rightarrow 2NO(g)+Cl_2(g)    \Delta H_2=2\times (+38.6kJ)=+77.2kJ

The expression for \Delta H_{rxn} will be,

\Delta H=\Delta H_1+\Delta H_2

\Delta H=(-180.6)+(+77.2)

\Delta H=-103.4kJ

Therefore, the value of \Delta H_{rxn} is, -103.4 kJ

Which part of an atom is actively exchanged or shared in a chemical bond?
denpristay [2]

The part of an atom that is actively exchanged or shared in a chemical bond is ELECTRON.

An atom is made up of three sub particles, which are electron, proton and neutron. The proton and the neutron are located in the nucleus of the atom and they make up the major mass of the atom. The electron is located outside of the nucleus and it orbit around the nucleus; it has negligible mass. The electron is negatively charged and because it is located outside of the nucleus, it is the one that is always involved in chemical reactions. There are different types of chemical bonds in chemical compounds and it is electrons that are normally used to form these bonds. During bond formation, electrons can either be donated or shared.
