Importance of Sample Papers
Solving sample papers is an important step in the process of exam preparation. When students solve sample papers, it helps them to understand how much they have understood from what they have learned. Solving model question papers helps students to check their level of preparation and gives them a reality check of where they stand. It also helps to develop writing practice and teaches time management.

How much electricity in terms of faraday is required to produce 40g of Al from molten Al2O3?
Ans. Given
Production of Al from Al2O3 has a reaction as following:
Al3+ + 3e- → Al
i.e. production of 1 mole of Al (27 g) from Al2O3 requires electricity = 3 F
or production of 1 g of Al from Al2O3 requires electricity = 3/27 F
So, production of 40 g of Al from Al2O3 requires electricity = 40/9 F
= 4.44 F
Q21. List the factors affecting the rate of reaction.
Ans. concentration of reactants & pressure in case of gases, temperature, and catalyst.
