The decomposition of dimethyl ether leads to the formation of (CH)_(4) and (H)_(2) and (CO) and the reaction rate is given by Rate =(k)[(CH)_(3) (OCH)_(3)]^(3 / 2) The rate of reaction is followed by increase in pressure in a closed vessel, so the rate can also be expressed in terms of the partial pressure of dimethyl ether, i.e., Rate= (k)P (C H)_(3) (OCH)_(3)^(3 / 2) If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?
