Question

ammonia is synthesized from dinitrogen and dihydrogen in the presenceof a metal catalyst. Fishel et al. used a constant volume reactor systemthat circulated the reactants over a heated ruthenium metal catalyst andthen immediately condensed the product ammonia in a cryogenic trap [c.T. Fishel, R. J. Davis, and J. M. Garces, J. Catal. 163(1996) 148]. A schematic diagram of the system is:

From the data presented in the following tables, determine the rates ofammonia synthesis (moles NH3 produced per min per gcat) at 350°Cover a supported ruthenium catalyst (0.20 g) and the orders of reactionwith respect to dinitrogen and dihydrogen. Pressures are referenced to298 K and the total volume of the system is 0.315 L. Assume that noammonia is present in the gas phase.
