33. The decomposition of dimethyl ether is a first order reaction with a rate constant of 3.2 x 104 1/s at 450 °C. CH₂OCH → CH4 +CO + H₂ Dimethyl ether gas is added to a container and the temperature is raised to 450 "C to give a concentration of 1.0 x 104 M. a. Sketch the structural formula for dimethyl ether, draw its Lewis structure and indicate the ideal bond angles. b. What is the initial rate that the reaction is preceding? c. What would be the concentration after 75 minutes? d. What would the rate after 75 minutes? e. How long would it take for the concentration to fall from the initial concentration to 1.0 x 105 M2 f. In a new experiment, but at the same temperature, the initial concentration of dimethyl ether is 5.0 x 10³ M, what would be the rate of reaction after 200 minutes? Answers: (b) 3.2 x 10 M/s; (c) 2.4 x 10 M, (d) 7.6 x 10° M/s; (e) 120 min, ( 3.4 x 10 M/s
