How would adding the catalyst nitrogen monoxide (no) affect this reaction? 2so2(g) + o2(g) → 2so3(g) a. no increases the rate at which so3 molecules are formed. b. no reacts with so3 to produce more so2 molecules. c. no decreases collisions between the so2 and o2 molecules. d. no increases the concentration of the so2 and o2 molecules. e. no increases the activation energy of the so2 and o2 molecules.

A

Explanation:

Because NO would increase the rate

The correct answer is Option A.

Explanation:

A catalyst is defined as the substance which increases the rate of the reaction without actually participating in the reaction.

This substance decreases the activation energy of the reactants, so as to proceed the reaction at a faster rate by increasing their effective collisions.

It does not affect the concentration of the reactants.

For the given reaction:

If we add NO, which is acting as a catalyst will increase the rate of the reaction to produce the products which is

Hence, the correct answer is Option A.

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
