Question

How many moles of potassium chlorate is to be heated to produce 11.2 litre oxygen?
(a) 1/2 mole
(b) 1/3 mole
(c) 1/4 mole
(d) 2/3 mole
​

Answer 1

here is a solution but different kind!

At NTP, 11.2 L of oxygen corresponds to  

22.4

11.2

​  

=0.5mol

2KClO  

3

​  

 

heat

​  

2KCl+3O  

2

​  

 

Thus, 2 moles of potassium chlorate on heating gives 3 moles of oxygen.

Thus,  

3

2

​  

×0.5=  

3

1

​  

 moles of potassium chlorate on heating gives 11.2 L of oxygen at NTP.

Hence, the correct option is B
