(choose chapter or problem)

A mixture of N2, H2 and NH3 is at equilibrium according to the equation N2(g) 1 3H2(g) 34 2NH3(g) as depicted below. (a) N2 H2 NH3 The volume is suddenly decreased (by increasing the external pressure), and a new equilibrium is established as depicted below. (b) a. If the volume of the final equilibrium mixture is 1.00 L, determine the value of the equilibrium constant K for the reaction. Assume temperature is constant. b. Determine the volume of the initial equilibrium mixture assuming a final equilibrium volume of 1.00 L and assuming a constant temperature. 103. A 4.72-g sample of methanol (CH3OH) was placed in an otherwise empty 1.00-L flask and heated to 250.8C to vaporize the methanol. Over time the methanol vapor decomposed by the following reaction: CH3OH(g) 34 CO(g) 1 2H2(g) After the system has reached equilibrium, a tiny hole is drilled in the side of the flask allowing gaseous compounds to effuse out of the flask. Measurements of the effusing gas show that it contains 33.0 times as much H2(g) as CH3OH(g). Calculate K for this reaction at 250.8C. 81982_ch06_0169-0196j.indd 9 9/18/15 1:47 PM Copyright 2017 Cengage Learning. All Rights Reserved.
