Consider the following elementary reaction:

CFCl3

(g)

→CFCl2

(g)

+Cl

(g)

Suppose we let

k1

stand for the rate constant of this reaction, and

k−1

stand for the rate constant of the reverse reaction.

Write an expression that gives the equilibrium concentration of

CFCl3

in terms of

k1

,

k−1

, and the equilibrium concentrations of

CFCl2

and

Cl

.

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
