The second-order rate constant for the decomposition of acetaldehyde has the values: T (K) 703 759 811 865
k (L mol-1s-1) 0.011 0.105 0.79 4.95
Using Arrhenius equation find (a) the activation energy and (b) pre-exponential factor.

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.  

possibly, yes.

explanation:

the amount of sugar you take in is dangerously high, risk of heart disease, high risk of diabetes, and etc.
