Question 1

Correct Answer:

Verified

a. Partially. It is right that the system will be apparently unchanging to a casual inspection once equilibrium is attained. However, macroscopic observation cannot determine if reaction has proceeded "as far as it will go"-which implies that it has stopped. Infact, it has not.

b. No. The reaction (in both directions) wil be observed to continue. However the rates in the two directions are equal, which explains the macroscopic observation of Part a.

Consider the reaction At equilibrium, [CO] = 4.14 × 10^-6 M; [Cl₂] = 4.14 × 10^-6 M; and [COCl₂] = 0.0627 M. Calculate the value of the equilibrium constant, K_c.
