Question

ammonia gas at 37 at ammonia gas at 37.0 °C. He then raises the temperature, and when the mixture has come to equilibrium measures the amount of hydrogen gas to be 4.1 mol Ammonia will decompose into nitrogen and hydrogen at high temperature. An industrial chemist studying this reaction fills a 25.0 L tank with 4.5 mol of Calculate the concentration equilibrium constant for the decomposition of ammonia at the final temperature of the mixture. Round your answer to 2 significant x10

Answer 1

Initi al concentration of NH, N 45 mol 25.0 L 1 = = 0.18M The ICE table constructed is as follows Initial (M) 0.18 Change (M): -2x Equil (M): 0.18-2x +3x According to the ICE table [H21a" .1 mol 0.164 M (3x) M = 25.0 L x 0.055 M Equilibrium concentrati on of NH, [NH,] (0.18-2x)M -(0.18-2(0.055))M-0.070 M Equilibrium concentration of N, .[N,]- (x)M - 0.055 M Equilibrium constant, K NH (0.055) (0.164) 0.070 0.049 - 4.9x102
