Which statement concerning the reversible reaction 2 NO2(g)
-
N204(9) is true?
NO2 is the product of the forward reaction.
OA
The reverse reaction produces N204.
At the start of the reaction, the forward and reverse reaction rates are equal.
As the forward reaction progresses and more N204 is formed, the reverse reaction rate increases.
D.

As the forward reaction progresses and more N204 is formed, the reverse reaction rate increases.

Explanation:

NO2 is not a product

Reverse reaction produce NO2

At the start of the reaction, rate of the forward one is more.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
