Textbook 5I Problem 15
Hi! In section 5I of the textbook, problem 15 gives us the initial concentration of one of the products and the the equilibrium constant, and then asks us to find the equilibrium constants of each of the products. The reaction takes place at 24 degrees Celsius, however I remember Dr. Lavelle saying in lecture that the reaction typically takes place at 25 degrees, and I was not sure if we need to take this temperature into account when calculating the equilibrium constant. Would this affect our procedure at all? Thank you!

Hi,
The reaction is indeed taking place at 24 degrees celsius and we usually look at reactions at 25 degrees celsius. However, there is no affect on the procedure of this problem since the Kc has already been given with the temperature already taken into account. Just use the Kc as you would normally do.

Re: Textbook 5I Problem 15
Hi Chiara! The value of the equilibrium constant (Kc) for a given reaction is dependent upon temperature. So when this problem 5I.15 tell us that Kc = 1.6 X 10^-4 for the reaction at 25 degrees Celsius, we know that the temp. is already accounted for in the equilibrium constant. His mention of 25 C was probably referring to the standard enthalpy of reaction conditions (for which a temp of 25 C is one of the conditions), but I'm not entirely sure. For this problem, you can solve the problem by setting up an ICE table and setting the final equilibrium concentrations of the products equal to the given Kc value; you dont need to account for the temp.
