After Frank Palko was sentenced to death by the state of Connecticut, the Supreme Court ruled that
GREYUIT [131]
<span>The answer is "his conviction and execution should be upheld". Frank Palko was first charged with murder and claimed that Connecticut violated the Double Jeopardy Clause of the Fifth Amendment. The fifth amendment states that "there must be no person to be put twice in jeopardy of life and limb" so this was the violation the court made after they charge him with murder for the second time. That's why when the second trial was made,he was sentenced to by the Supreme court which decided that he should be executed and convicted because of the evidences found.</span>

The activation energy for the reaction NO2 (g )+ CO (g) ⟶ NO (g) + CO2 (g) is Ea = 218 kJ/mol and the change in enthalpy for the
madreJ [45]

Answer:

470\frac{KJ}{mol}

Explanation:

The activation energy represents the energy barrier that reagents must pass to transform into products (or products to transform into reagents in a reverse reaction)

For any reaction, the change in enthalpy is related to the activation energy by the equation

\Delta H =E_{a\ direct}-E_{a\ reverse}

So, the activation energy for the reverse reaction is

E_{a\ reverse}=E_{a\ direct}-\Delta H =218 \frac{KJ}{mol} - (-252)\frac{KJ}{mol}=470\frac{KJ}{mol}

1. How much energy must be absorbed to break the bonds of the 2 molecules of HCl?
IRISSAK [1]

Bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.

<h3>What is Bond energy?</h3>

The term bond energy refers to the energy that must be taken in to break a bond. It is also the energy required to form the bond.

The energy that must be supplied to break the bonds in two molecules of HCl is 862 J. The energy released is obtained from; 862J - [436 +262] = 164J.

The total energy of the reaction is 164J, this is called the enthalpy change. Based on this value of the total energy, the reaction is endothermic. Hence, it is true that; "It takes more energy to break the two H–Cl bonds than is released when forming the H–H and Cl–Cl bonds."
