The decomposition of dimethyl ether leads to the formation of CH4, H2
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, so the rate can also be expressed in terms of the partial pressure
of dimethyl ether, i e ,
