Matching Processes with Catalysts:

o   (a) Deacon's process: CuCl? used as catalyst

o   (b) Contact process: V? O? used as catalyst

o   (c) Cracking of hydrocarbon: ZSM-5 used as catalyst

o   (d) Hydrogenation of vegetable oil: Particles Ni used as catalyst

Matching Compounds to their Class:

o   Antacid: Cimetidine

o   Artificial Sweetener: Alitame

o   Antifertility: Novestrol

o   Tranquilizers: Valium

Reaction Sequence:

o   NO? + CH? COOH → HNO? + CH? COO?

o   Sulphanilic acid (+ NH? CH? COO? ) + HNO? → N-acetylated diazonium intermediate + 2H? O

The intermediate + another molecule → Red Azodye + NH? + CH? COOH

Eutrophication is the process in which a water body becomes overly enriched with nutrients, leading to the plentiful growth of simple plant life.

Unimolecular Reactions might seem to not participate in the collision theory due to the presence of only a single molecule. In such cases, the molecule is activated by external forces such as heat, light, electricity, or by colliding with the walls of the container. This force charges the molecule enough to break the activation barrier and result in an effective collision.

100 mol of KBr is doped with 10? mol of SrBr?

Therefore, 1 mol of KBr contains 10? mol of SrBr?

Molar mass of KBr = 119 g/mol .

119 g of KBr contains 10? mol of SrBr?

1 g of KBr contains (10? / 119) mol of SrBr?

Each Sr²? ion introduced creates one cation vacancy to maintain electrical neutrality.

Number of cation vacancies = (moles of SrBr? ) * (Avogadro's number)

Number of vacancies = (10? / 119) * (6.023 * 10²³) = 5.06 * 10¹?

The answer provided in the document is "5 (Rounded off)", which likely refers to the coefficient 5.06.
