Question

Statement 1: Primary cell can be recharged by passing an electric current through them.
Statement 2: Secondary cells are those in which the energy produced from the combustion of fuels is directly converted into electrical energy.

• A. Statement 1 is True, Statement 2 is False
• B. Statement 2 is True, Statement 1 is False
• C. Both the statements are True
• D. Both the statements are false

Answer 1

The correct option is D Both the statements are false

We discussed about various types of commercial cells.
Let’s recall the classification.
Various commercial cells may be classified mainly into the following three types: (a) primary cells, (b) secondary cells, and (c) fuel cells.
Primary cells are those in which the redox reaction occurs only once and the cell becomes dead after some time, and cannot be used again. Two common examples of this type are dry cell and mercury cell.
Secondary cells are those which can be recharged by passing an electric current through them and hence can be used over and again. Two well-known examples of this type are lead storage battery and nickel-cadmium storage cell.
Fuel cells are those in which the energy produced from the combustion of fuels such as $H_2,CO,C{H}_4$, etc., is directly converted into electrical energy. Such a conversion is possible because combustion reactions are also redox reactions.
Now, if we have to remember it.
Primary Cell $\Rightarrow$ Cell becomes dead after sometime and non rechargeable.
Secondary Cell $\Rightarrow$ Rechargeable
Fuel Cell $\Rightarrow$ the name itself suggests its definition.
Therefore, both the statements are false.
