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

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. (Ans.: k = 0.00048 min–1) (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?
