The gas phase decomposition of dimethyl ether at 500 °C CH;OCH;(g) CH4(g) + H2(g) + CO(g) is first order in CH3OCH3. During one experiment it was found that when the initial concentration of CH3OCH3 was 0.141 M, the concentration of CH;OCH, dropped to 4.00×10-² M after 2017 s had passed. Based on this experiment, the rate constant for the reaction is
