Ammonia is oxidized to nitric oxide in the following reaction: 4nh3 5o2 ! 4no 6h2o (a) calculate the ratio (lb-mole o2 react/lb-mole no formed). (b) if ammonia is fed to a continuous reactor at a rate of 100.0 kmol nh3/h, what oxygen feed rate (kmol/h) would correspond to 40.0% excess o2? (c) if 50.0 kg of ammonia and 100.0 kg of oxygen are fed to a batch reactor, determine the limiting reactant, the percentage by which the other reactant is in excess, and the extent of reaction and mass of no produced (kg) if the reaction proceeds to completion.

E=n⋅h⋅ν (energy = number of photons times Planck's constant times the frequency), if you divide the energy by Planck's constant, you should get photons per second. Eh=n⋅ν → the term n⋅ν should have units of photons/second.

Explanation:

Hope this helps
