In an experiment, the rate constant is determined to be 3.29103 s 1 at 543C. (a) Calculate the half-life of the reaction at 543C based on this experiment. (b) If the initial partial pressure of CH3OCH3 in a container at 543C is 3.84 atm, how long will it take to fall to 0.480 atm? 3 item attempts remaining
