Which one of the following statements is not correct about zeolites?
Which one of the following statements about the zeolites is false?
Zeolites are aluminosilicates having the three-dimensional open structure in which four or six-membered rings predominates.
Thus, due to an open-chain structure, they have cavities and can take up water and other small molecules. Also, they consist of a crystalline structure formed from $$SiO_{4}^{4-}$$ and $$AlO_4^{5-}$$ only.
Which one of the following statements is not correct about zeolites?
Which of the following are correct?
Describe some features of catalysis by zeolites.
What is shape selective catalysis?
Which of the following statements about zeolites is not correct?
Shape-selective catalysis is a reaction catalysed by:
The average degree of freedom per molecule for a gas are $$6$$. The gas performs $$25 J$$ of work when it expands at a constant pressure. The heat absorbed by gas is
Give an example of shape-selective catalyst.
