The following phase diagram shows how a catalyst affected the rate of a reaction.

which statement below best describes how the catalyst affected the reaction shown in this diagram?

a. the catalyst decreased the activation energy of the reactants.
b. the catalyst increased the activation energy of the reactants.
c. the catalyst increased activation energy of the products.
d. the catalyst decreased activation energy of the products.

The correct answer is "The catalyst decreased the activation energy of the reactants."

Explanation:

Activation energy is the minimum energy required to start a reaction. A catalyst lowers the activation energy of a reaction. Here the catalyst lowers the activation energy of the reactant, thus making it easier to start to the reaction. In the absence of a catalyst the activation energy of the reactant will be higher.

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.
