This statement is false because two oxygen atoms are equally electron hungry and equally share their electrons.

<h3>Oxygen </h3>

The chemical element with the letters O and the atomic number 8 is called oxygen. It belongs to the chalcogen group of the periodic table and is a highly reactive nonmetal that rapidly forms oxides with most elements as well as with other compounds. The third-most plentiful element in the universe after helium and hydrogen is oxygen, which is also the most abundant element on Earth. Dioxygen, a colorless and odorless diatomic gas with the formula O2, is created when two of the element's atoms combine at standard temperature and pressure. Although this has changed significantly over time, diatomic oxygen gas currently makes up 20.95% of the Earth's atmosphere. Nearly 50% of the Earth's crust is made up of oxides, which contain oxygen.

Nucleophilicity is a kinetic property. A higher nucleophilicity indicates that the nucleophile will easily donate its electrons
lord [1]

The rate constant (K) is related to activation energy (Ea), frequency factor (A) and temperature (T) in Kelvin by the equation

R = molar gas constant

K = A(e^(-Ea/RT))

Taking natural log of both sides

In K = In A - (Ea/RT)

In K = (-Ea/R)(1/T) + In A

Comparing this to the equation of a straight line; y = mx + c

y = In K, slope, m = (-Ea/R), x = (1/T) and intercept, c = In A

a) From the question, m = (-Ea/R) = -1.10 × (10^4) K

(-Ea/R) = -1.10 × (10^4) = -11000

R = 8.314 J/K.mol

Ea = -11000 × 8.314 = 91454 J/mol = 91.454 KJ/mol

b) c = In A = 33.5

A = e^33.5 = (3.54 × (10^14))/s

c) K = A(e^(-Ea/RT))

A = (3.54 × (10^14))/s, Ea = 91454 J/mol, T = 25°C = 298.15 K, R = 8.314 J/K.mol

K = (3.54 × (10^14))(e^(-91454/(8.314×298.15))) = 0.0336/s

What are the two variables that affect the electric force between two objects?
givi [52]

Explanation:

The electrical force between two objects is given by the formula as follows :

F=\dfrac{kq_1q_2}{d^2}

k is electrostatic constant

q₁ and q₂ are electric charges

d is distance between charges

So, the two force between two charged objects depends on the product of charges and distance between charges.
