The decomposition of dimethyl ether leads to the formation of C H 4 , H 2
= k [ C H 3 O C H 3 ] 3 ∕ 2
The rate of reaction is followed by increase in pressure in closed vessel, sothe rate can also be expressed in terms of the partial pressure of dimethylether, i.e.,
= k [ p C H 3 O C H 3 ] 3 ∕ 2
If the pressure is measured in bar and time in minutes, then what are theunits of rate and rate constants ?

If the pressure is measured in bar and time in minutes, then what are theunits of rate and rate constants ?
Solution:
In terms of pressure,
Units of rate = bar min– 1
Units ofk =
=
= b a r − 1 ∕ 2 min − 1
Units of rate = bar min
Units of
