Question

Nitrogen reacts with hydrogen to form ammonia gas. Out of the given necessary condition, which one is not required? one.Fe & M o two.200-900 atm three.500 Degree Celcius four.MnO2

Answer 1

Answer:

Knowledge of effective diffusion coefficients in char particles is important when interpreting experimental reactivity measurements and modeling char combustion or NO and N2O reduction. In this work, NO and N2O reaction with a bituminous coal char was studied in a fixed-bed quartz glass reactor....... In the case of strong pore diffusion limitations, the error in the interpretation of experimental results using the mean pore radius could be a factor of 5 on the intrinsic rate constant. For an average coal char reacting with oxygen at 1300 K, this would be the case for particle sizes larger than about 50...

Answer 2

Answer:

MnO2

Explanation:

This is because it doesn't supports it.
