Answer
A is true but R is false.
Explanation— Catalytic oxidation of Ammonia by Ostwald's process does not require any external heat because the reaction itself is exothermic and the heat evolved maintains the temperature of the catalytic chamber. Hence, the assertion (A) is true.
Catalytic oxidation of ammonia is an exothermic process. Hence, the reason (R) is false.
