Both the statements are incorrect.
Hydrolysis of sucrose in the presence of dilute hydrochloric acid is an example of homogeneous catalysis.
Rate of physisorption increases with decrease in temperature.
Choose the incorrect statements.1. Zeolites are aluminosilicates havi...
Incorrect statements:
b) 1 and 3
Explanation:
1. Zeolites are aluminosilicates having three-dimensional network.
Zeolites are crystalline aluminosilicate minerals that have a three-dimensional network structure. They contain aluminum, silicon, and oxygen in their framework, with other elements and ions present as well. This statement is correct.
2. Hydrolysis of sucrose in the presence of dilute hydrochloric acid is an example of heterogeneous catalysis.
Heterogeneous catalysis involves a catalyst that is in a different phase than the reactants. In the case of the hydrolysis of sucrose in the presence of dilute hydrochloric acid, both the sucrose and the hydrochloric acid are in the liquid phase, making it an example of homogeneous catalysis rather than heterogeneous catalysis. Therefore, this statement is incorrect.
3. Rate of physisorption decreases with decrease in temperature.
Physisorption is the physical adsorption of gas molecules onto a solid surface. It is a weak type of adsorption that occurs due to van der Waals forces. The rate of physisorption generally increases with a decrease in temperature because at lower temperatures, the gas molecules have lower kinetic energy and are more likely to be attracted to the solid surface. Therefore, this statement is incorrect.
4. More easily liquefiable gases are adsorbed readily.
Easily liquefiable gases have stronger intermolecular forces, which make them more likely to be adsorbed onto a solid surface. Therefore, this statement is correct.
In conclusion, the incorrect statements are:
- Hydrolysis of sucrose in the presence of dilute hydrochloric acid is an example of heterogeneous catalysis.
- Rate of physisorption decreases with decrease in temperature.
Therefore, the correct option is c) 2 and 3.
