Expert Answer
(a)

2CO + O2 →   2CO2

2 V     1 V      2 V  

 

2 V of CO requires = 1V of O2

so, 100 litres of CO requires = 50 litre of O2
 
(b)

2H2 + O2    → 2H2O   

2 V     1V        2V

 

From the equation, 2V of hydrogen reacts with 1V of oxygen

so 200cm3 of Hydrogen reacts with = 200/2= 100 cm3

 

Hence, the unreacted oxygen is 150 - 100 = 50cm3 of oxygen.
