Answer: The electronic configuration of Chlorine is $1s^22s^22p^63s^23p^5$

Explanation: Electronic configuration is the distribution of electrons of an atom of molecule in atomic or molecular orbitals respectively.

Chlorine is an element present in group 17 of the periodic table. It's atomic number is 17.

Number of electrons = Atomic number

Number of electrons in Cl atom = 17

Electronic configuration of Cl will be $1s^22s^22p^63s^23p^5$

Answer:

High activation energy is the reason behind unsuccessful reaction.

Explanation:

There are two types of reaction: (1) thermodynamically controlled reaction and (2) kinetically controlled reaction.

Thermodynamically controlled reaction are associated with change in enthalpy during reaction. More negative the enthalpy change, more favored will be the reaction.

Kinetically controlled reaction are associated with activation energy of a reaction. The lower the activation energy value, the more rapid will be the reaction.

Here, reaction between $CCl_{4}$ and $H_{2}O$ is thermodynamically favored due to negative enthalpy change but the high activation energy does not allow the reaction to take place by simple mixing.
