`2NOBr rarr 2NO(g)+Br_2(g)`
Rate=`k[NOBr]_2`
What are the units of rate constant.?

Text Solution

Verified by Experts

As rate is given by
Rate = `k[NCBr]_2`
`therefore` Order with respect to NOBr =2
Overall order =2
To find units of k
`K=("Rate")/([NOBr]^2)`
units of k= `(mol L^(-1)s^(-1))/((molL^(-1)^2)`
`(s^(-1))/(mol L^(-1))`
`=mol^(-1)" L "s^(-1)`

The decomposition of dimethyl ether leads to the formation of CH_4, H_2 and CO and the reaction rate is given by Rate = k [CH_3OCH_3]^(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., Rate= k (P_(CH_3OCH_3 )^(3/2) If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?
