I tried to do the question below and I want to make sure if I did correctly.
The question is:
Ions B and C react to form complex BC. If 15.0 mL of 1.00 M B is combined with 15.0 mL of 1.00 M C, 0.00450 mol of complex BC is formed. Determine the equilibrium constant for this reaction.
Firstly, I converted the total volume 15.0 mL + 15.0 mL = 30 mL to L and I got 0.03L
Secondly, I used the given 0.00450 mol and divided it by 0.03 L and I got 0.15 M for BC
Thirdly, I did the ICE chart
After that, I used the quadratic formula to solve for x and calculate the concentration for each substance, as well as getting the Kc at equilibrium
I got 1.53 for Kc but I am not sure if the whole process is correctly done. Please point out my mistakes, thank you very much.
