An aqueous mixture of phenol and ammonia has initial concentrations of 0.200 M C

Question

An aqueous mixture of phenol and ammonia has initial concentrations of 0.200 M C_6H_5OH(aq) and 0.120 M NH_3(aq). At equilibrium, the C_6H_5O^-(aq) concentration is 0.050 M. Calculate K for the reaction C_6H_5OH(aq) + NH_3(aq) reversible C_6H_5O^- + NH^+_4(aq) 0.10 0.24 2.1 4.2 Assume that the following chemical reaction is at equilibrium. 2 IC1 (g) reversible I_2(g) + Cl_2(g) delta H^ degree = +26.9 kJ At 25 degree C, K_p = 2.0 x 10^5. If the temperature is increase to 45 degree C, which statement applies K_p will decrease and the reaction will proceed in the backward direction. K_p will decrease and the reaction will proceed in the forward direction. K_p will remain unchanged and the reaction will proceed in the forward direction. K_p will increase and the reaction will proceed in the forward direction.
