Compound A undergoes a reversible isomerization reaction A ⇌ B over a supported metal catalyst. Under reaction conditions, A and B are both liquids with nearly identical density. The equilibrium constant based on concentration is 5.8. In a packed-bedPFR, a feed of pure A undergoes a net conversion to B of 55%. The reaction is first order in both directions as determined from experimental data. If a second, identical flow reactor at the same temperature is placed downstream from the first, what overall conversion would you expect if:

a. The reactors are directly connected in series.
b. The product from the first reactor are separated by appropriate processing and only the unconverted A is fed to the second reactor?

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
