The decomposition of ammonia to nitrogen and hydrogen on a tungsten filament at 800°C is independent of the concentration of ammonia at high pressures of ammonia.What is the order of the reaction with respect to ammonia?

Question

Quizplus · Accepted Answer

The fact that the decomposition of ammonia is independent of the concentration of ammonia at high pressures suggests that the rate of the reaction is not affected by the concentration of ammonia. This is a characteristic of zero-order reactions, where the rate is constant and independent of the concentration of the reactant. Therefore, the order of the reaction with respect to ammonia is zero.
