Question

Chapter 13, Question 14 Parameterization A chemist is studying the rate of the Haber synthesis: N2 + 3H2 2 NH3 Starting with a closed reactor containing 1.25 mol/L of N, and 0.50 mol/L of H7, the chemist finds that the Hy concentration has fallen to 0.25 mol/L in 46 seconds. What is the relative rate of reaction over this time? M/S the tolerance is +/-2% What is the average rate of NH3 production? M/S the tolerance is +/-2% LINK TO TEXT

Answer 1

2 Non No + 3H₂ to 1.25m 0.50m t= 46 sec. (1.25-2M (0.50-3x)m anm. 0.50-32= 0.25 a=0.25 0.25-0.50 4.6 - mis e t 46 rate of the reaction = -1 [H2] - 3 At = -1 = 1.812 x 103 mob.
