An aqueous mixture of phenol and ammonia has initial concentrations of 0.302 M C6H5OH(aq) and 0.139 M NH3(aq). At equilibrium, the C6H5O–(aq) concentration is 5.00E-2 M. Calculate K for the reaction.

Explanation:

1. Chemical equilibrium equation

2. ICE (initial, change, equilibrium) table

Molar concentrations:

I                0.302            0.139                 0                   0

C            - 0.0500         - 0.0500         + 0.0500      + 0.0500

E               0.252            0.0890            0.0500          0.0500

3. Constant equilibrium equation:

the answer is b & c i believe : )
