The decomposition of dimethyl ether leads to the formation of CH4, H2 and CO and the reaction rate is given by
Rate $= k \left[ CH _3 OCH _3\right]^{3 / 2}$
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 $= k \left( p _{ CH _3 OCH _3}\right)^{3 / 2}$
If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?
