Acooling system is used to remove the excess energy from an exothermic reaction in a polymerization reactor, shown below. the temperature in the reactor increases drastically because of failure of the cooling system fails in the process which leads to an increase in reaction rate and additional energy release. the ultimate end result is a runaway situation in the process with pressures exceeding the threshold limit of the reactor pressure vessel. a safety control valve has to be installed to manipulate the cooling water by considering the control loop concept. perform hazop study on the (15 marks) reactor to enhance the safety of the process.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
