Question

Exercise 16.83 Ammonia can be synthesized according to the following reaction: N2 (g) 3H2 (g) 2 NH3(g) Kp 5.3 x 10 5 at 725 K A 200.0-L reaction container initially contains 1.27 kg of N2 and 0.310 kg of H2 at 725 K. Part A Assuming ideal gas behavior, calculate the mass of NH3 (in g) present in the reaction mixture at equilibrium. Express your answer using two significant figures m 310 g Submit My Answers Give Up Correct Part B What is the percent yield of the reaction under these conditions? Express your answer using two significant figures Submit My Answers Give Up

Explanation / Answer

N2 +3 H2 -----------> 2 NH3

28gm + 6 gm --------------> 34gm

1.27 kg + 0.310 kg -------------> 1.54 kg of NH3 as N2 is the limiting reagent here

now % yield = 310 / 1540 * 100 = 20.1 %
