Cracking , Cracking is the name given to breaking up large hydrocarbon molecules into smaller and more useful bits. This is achieved by using high pressures and temperatures without a catalyst, or lower temperatures and pressures in the presence of a catalyst.
Catalytic cracking requires specific conditions such as high temperature (typically between 450-550°C) and moderate pressure. The presence of a catalyst, usually a solid acid catalyst like zeolite, is essential to facilitate the breaking of larger hydrocarbon molecules into smaller, more valuable products like gasoline and diesel. Additionally, a controlled feedstock composition and proper residence time in the reactor are important for optimizing the cracking process.
The specific protein molecule in a cell acts as a catalyst, facilitating the chemical reaction to occur more efficiently or at a faster rate. The protein molecule binds with the reactants, stabilizes the transition state, and lowers the activation energy required for the reaction to proceed. Without the presence of this protein molecule, the reaction may occur, but at a significantly slower rate.
A triglyceride molecule has 3 fatty acid tails attached to a glycerol backbone, and these fatty acid tails can be either saturated or unsaturated depending on the presence of double bonds in the hydrocarbon chain.
The major organic product formed when 3-heptyne is hydrogenated in the presence of Lindlar's catalyst is 3-heptene. Lindlar's catalyst is a poisoned palladium catalyst that selectively reduces alkynes to cis alkenes.
The reaction of an alkene and water in the presence of an acid catalyst is called an acid-catalyzed hydration reaction. This reaction forms an alcohol.

The two necessary conditions for cracking to take place are high temperature and presence of a catalyst. High temperature allows for the breaking of chemical bonds in the hydrocarbon molecules, while the catalyst accelerates the cracking reaction by providing an alternative pathway with lower activation energy.
The alkene to alkane reaction occurs through a process called hydrogenation, where hydrogen gas is added to the alkene molecule in the presence of a catalyst, such as platinum or palladium. This results in the breaking of the double bond in the alkene, converting it into a single bond in the alkane.
The process by which a molecule gains an H atom is called hydrogenation. It involves the addition of a hydrogen atom to a molecule typically in the presence of a catalyst, such as a metal like platinum or nickel. This process can alter the physical and chemical properties of the molecule.
Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.cellular respiration- process that release energy by breaking down glucose and food molecule in the presence of oxygen.
Hydrocarbons typically do not react with acids under normal conditions. However, in the presence of a strong acid or a catalyst, hydrocarbons can undergo reactions such as acid-catalyzed hydration to form alcohol or ester formation.

It can NOT be changed by the presence of hydrogen without chemical reaction.
Two conditions needed to crack paraffin are high temperature (around 500-900 degrees Celsius) and the presence of a suitable catalyst. Cracking breaks down larger hydrocarbon molecules like paraffin into smaller, more valuable hydrocarbons like ethylene and propylene.
A hydrocracker is a high-pressure, high-temperature catalytic reactor that uses hydrogen in the presence of a catalyst to break down heavy hydrocarbon molecules into lighter and more valuable products like gasoline and diesel. The process involves breaking carbon-carbon bonds and saturating carbon-carbon double bonds with hydrogen, resulting in improved fuel quality and increased yield of valuable products.
