Elanso [62]

Answer is: a. Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.

The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).

Alkaline metals (group 1), in this example rubidium, have lowest ionizations energy and easy remove valence electrons (one electron), they are most reactive metals.

Earth alkaline metals (group 2), in this example strontium, have higher ionization energy than alkaline metals, because they have two valence electrons, they are less reactive.

Rubidium electron configuration: ₃₇Rb 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s¹; one valence electron is 5s¹ orbital.

Strontium electron configuration: ₃₈Sr 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s²; two valence electrons is 5s² orbital.

The vapor flowrate will vary with time by ; gradually increasing from zero to one half of the molar feed flow rate and then remain constant ( C )

<u>Although the options related to your question is missing attached below are the missing options </u>

<u />

Vapor flow rate is the amount of vapor per unit of time that flows through a specific area at a given time .

Given that the stream consists of 48.9 mole% of benzene and 51.1% toluene fed at a constant rate into a process unit. The vapor flowrate will vary with time because it will gradually increase from zero to 1/2 of the molar feed flow rate before it will remain constant.

Hence we can conclude that The vapor flowrate will vary with time by gradually increasing from zero to one half of the molar feed flow rate and then remain constant.
