Select the correct statements:a)Activation energy is zero in physical ...
Explanation:
Activation energy is zero in physical adsorption:
This statement is incorrect. Activation energy is the minimum energy required for a chemical reaction to occur. Physical adsorption involves weak intermolecular forces, such as Van der Waals forces, which do not require activation energy. However, chemical adsorption involves the formation of chemical bonds, which require activation energy.
Activation energy is required for chemical adsorption:
This statement is correct. Chemical adsorption involves the formation of chemical bonds between the adsorbent and the adsorbate. To break the existing bonds and form new bonds, activation energy is required. This energy barrier must be overcome for the reaction to proceed.
Faujasite is shape selective catalyst:
This statement is correct. Faujasite is a type of zeolite, which is a shape-selective catalyst. Zeolites have a unique porous structure with uniform pore sizes, allowing them to selectively adsorb and catalyze molecules based on their size and shape. Faujasite, in particular, has a large pore size, making it suitable for catalyzing reactions involving bulky molecules.
Catalyst provides a new pathway for reaction, by taking part in it:
This statement is correct. A catalyst is a substance that speeds up a chemical reaction by providing an alternative reaction pathway with a lower activation energy. It does not undergo any permanent chemical change during the reaction and can be used repeatedly. By lowering the activation energy, a catalyst facilitates the formation of the transition state, making it easier for the reactants to convert into products. This allows the reaction to occur more rapidly and at lower temperatures.
In summary, all of the statements (a, b, c, and d) are correct. Activation energy is required for chemical adsorption, Faujasite is a shape-selective catalyst, and catalysts provide a new pathway for reactions by taking part in them.
