Answer:
B = (2.953 × 10⁻⁹⁵) N.m⁹
Explanation:
At equilibrium, where the distance between the two ions (ro) is the sum of their ionic radii, the force between the two ions is zero.
That is,
Fa + Fr = 0
Fa = - Fr
Fa = (|q₁q₂|)/(4πε₀r²)
Fr = -B/(r^n) but n = 9
Fr = -B/r⁹
(|q₁q₂|)/(4πε₀r²) = (B/r⁹)
|q₁| = |q₂| = (1.6 × 10⁻¹⁹) C
(1/4πε₀) = k = (8.99 × 10⁹) Nm²/C²
r = 0.097 + 0.181 = 0.278 nm = (2.78 × 10⁻¹⁰) m
(k|q₁q₂|)/(r²) = (B/r⁹)
(k × |q₁q₂|) = (B/r⁷)
B = (k × |q₁q₂| × r⁷)
B = [8.99 × 10⁹ × 1.6 × 10⁻¹⁹ × 1.6 × 10⁻¹⁹ × (2.78 × 10⁻¹⁰)⁷]
B = (2.953 × 10⁻⁹⁵) N.m⁹
Hey :)
Air pollution
Hope this helps!
Good luck in your test :)
It would be D light dependent reaction, I don’t have much of a explanation but I promise it’s D
Answer: Option (b) and (d) are the correct answer.
Explanation:
Kinetic products are defined as the products which contain a terminal double bond and the reaction is irreversible in nature.
Kinetic controlled products are formed faster because these tend to lower the activation energy. Due to this molecules with less energy are also able to participate in the reaction.
Therefore, rate of reaction increases leading to rapid formation of products.
Therefore, we can conclude that the products of a reaction under kinetic control are product that is formed at the fastest rate and product whose formation requires the smallest free energy of activation.
