The following data were reported [C. N. Hinshelwood and P. J. Ackey, Proc. R. Soc. (Lond)., A115, 215] for a gas-phase constant-volume decomposition of dimethyl ether at 504°C in a batch reactor. Initially, only (CH3)2O was present.

(a) Why do you think the total pressure measurement at t = 0 is missing? Can you estimate it?

---

(b) Assuming that the reaction

is irreversible and goes virtually to completion, determine the reaction order and specific reaction rate k.

---

(c) What experimental conditions would you suggest if you were to obtain more data?

---

(d) How would the data and your answers change if the reaction were run at a higher temperature? A lower temperature?
