Question

Consider the equilibrium system described by the chemical reaction below. For this reaction, Kc = 2.19 × 10^-10 at a particular temperature. Calculate the value of Qc for the initial set reaction conditions: 4.50 × 10^- 2 M COCI2, 1.10 × 10^-7 M CO, 2.25 × 10^-6 M CI2.

Answer 1

Q value is just the initial values of the concentrations input into the K expression (.i.e. the Q value will determine which way the reactions will go in order to reach the K value at equilibrium)

Q = [CO][Cl₂]/[COCl₂] Just plug in the values given.
