Textbook Question 5I.23

[Charlize Choo 1G]

For 5I.23, I set up my ICE Table and use the change in concentration (x) as 0.0478. When I calculate Kc, I get 3.91 but the textbook says the answer is 3.88. Is this a rounding error or am I doing the question wrong?

hi!
From your response, my best guess is that there is a rounding error somewhere in there. I have attached my work to demonstrate how to get Kc = 3.88 so you can compare it to your work process.
I hope this helps :)
