The decomposition of dimethyl ether leads to the formation of CH4,H2 and CO and the reaction rate is given
By rate = K[CH3OCH3]32
The rate of reaction is followed by increase in pressure in a closed vessel and the rate can be expressed in terms of the partial pressure of dimethyl ether i.e, Rate = K(pCH3OCH3)32
If pressure is measured in bar and time in minutes, the units of rate constant are
