In this case
k = x min−1 and [A0]
= 0.01M = 1 × 10−2M
t = 1 hour = 60 min
[A]= 1 × 10−2 ( e−60x)
Lewis developed electronic theory of valence or theory of chemical bonding to explain the formation of chemical bond between the two atoms.
According to the electronic theory of valence, every atom tries to attain octet configuration (presence of eight electrons) in its valence shell by losing or gaining or by sharing of electrons. This is known as the "Octet Rule".
The electrostatic forces of attraction that holds the two oppositely charged ions together are known as "electrovalent bond".
