The correct sequence of atomic weights is Cobalt (58.933) > Nickel (58.693) > Iron (55.847), which is option 2.

Carbon dating is a radiometric dating method that uses the decay rate of radioactive carbon-14 to estimate the age of organic materials, including those from the prehistoric period.

The addition of 2% gypsum in cement acts as a retarding agent, preventing the rapid hardening of the mixture. This allows the cement to set at a slower rate, resulting in a stronger and more durable final product.

The Wacker process involves the oxidation of ethylene to ethanal using a palladium chloride catalyst. Copper(II) chloride (CuCl2) acts as a promoter or co-catalyst in this reaction, facilitating the regeneration of the palladium catalyst and enabling the efficient production of ethanal.

Cracking is a process where large molecules break down into smaller ones. At low temperatures and pressures, a catalyst like Al2O3 and SiO2 is required to facilitate this reaction.

In chemistry, the process of converting reactants into products in a specific time period is described by the rate of forward reaction. This term represents the speed at which the reaction progresses. The other options, such as rate constant and rate co-efficient, are related to reaction rates but refer to different aspects of the reaction rate equation. The rate constant determines the strength of a reaction, while the rate co-efficient is a proportionality constant in the rate law equation.
