An aquecous mixture of phenol and ammonia has initial concentrates of 0.200 M C_3OH (aq) and 0.120 M NH_3(aq). At equilibrium, the C_6H_5O^+ (aq) concentration is 0.050 M. Calculate K for the ration. C_6H_5OH (aq) + NH_3(aq) = C_6H_5O^- + NH_4^+ (aq) a. 0.10 b. 0.24 c. 2.1 d. 4.2 e. 4.8 The equilibrium constant, K_e for the decomposition of ammonium hydrogen is 1.8 times 10^-4 at 25 degree C NH_4HS9s) NH_3(g) + H_2S(g) If excess NH_4HS(s) is allowed to equilibrate at 25 degree C, what is the equilibrium concentration of NH3? a. 3.2 times 10^-8 M b. 9.0 times 10^-5 M c. 1.8 times 10^-4 d. 6.7 times 10^-3 M e. 1.3 times 10^-2 M
