Transcribed Image Text: Question 3.
(a) In an aqueous solution of CH3NH3 the following equilibrium is established.
CH;NH3 (aq) + H2O (1)
CH3NH3* (aq) + OH° (aq)
Determine Kc for this equilibrium at 298 K if the initial concentration of CH3NH3 is 0.1 M
and at equilibrium the concentration of OH is 0.0066 M. Transcribed Image Text: (b) A chemist mixes CH4 and H2O in a 0.32 L flask at 1200 K. At equilibrium, the flask
contains 0.26 mol of CO, 0.091 mol of H2, 0.041 mol of CH4. What is the concentration
of the water vapour at equilibrium, Kc = 0.26.
