The decomposition of dimethyl ether leads to 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 an 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[pCH3OCH3]3/2. If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?
Rate of given chemical reaction will be represented as
.
Hence units of rate is bar min-1
To find units of K, K = rate/[pCH3OCH3]3/2
The unit of k = bar -1/2min-1.
Units of Rate- bar min-1. and Units of Rate constant K : bar -1/2min -1
