Answer
A is true but R is false.
Explanation — In the Haber's process of manufacturing ammonia, nitrogen and hydrogen are used as reactants. Where, hydrogen is obtained as water gas from Bosch process. Hence, the assertion (A) is true.
The ratio of reactants nitrogen and hydrogen in the Haber's process is 1 : 3. One volume of nitrogen (from liquid air) and three volume of hydrogen (water gas from Bosch process). Hence, reason (R) is false.
