The decomposition of dimethyl ether leads to the formation of  and CO and the reaction rate is given by Rate = k [CH3OCH3]3/2. The rate of reaction is followed by increase in pressure in a closed vessel and the rate can also be expressed in terms of the partial pressure dimethyl ether i.e. rate = k (pCH3OCH3)3/2. If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?  

Answer:

Units of rate of the reaction Units of rate constant; Rate = k [Pressure]3/2
