Question -

The decomposition of dimethyl ether leads to the formation of CH_4, H_2 and CO and the reaction rate is given by



Answer -

Rate = [CH3OCH3]3/2

The rateof reaction is followed by increase in pressure in a closed vessel, so the ratecan also be expressed in terms of the partial pressure of dimethyl ether, i.e.,

If the pressure is measured inbar andtime in minutes, then whatare the units of rate and rate constants?

Answer

If pressure is measured in bar and time in minutes,then

Unit of rate = bar min−1
