Textbook Question
Chapter 24.7, Problem 24.8.1PE
At 800 K, the equilibrium constant for the reaction A2 (g) ⇌2A (g) is Kc = 3.1 X 10-4.
- Assuming both forward and reverse reactions are elementary reactions, which rate constant do you expect to be larger, Kf or Kr?
- If the value of Kf = 0.27 s-1, what is the value of Kr at 800K?
- Based on the nature of the reaction, do you expect the forward reaction to ne endothermic or exothermic?
- If the temperature is raised to 1000 K, will the reverse rate constant K, increase or decrease? Will the change in Kr be larger or smaller than the change in Kf? a
