What will be the effect of temperature on rate constant?
The rate constant of a reaction is nearly doubled with a $10^{\circ}$ rise in temperature. However, the exact dependence of the rate of a chemical reaction on temperature is given by Arrhenius equation,
$k= Ae ^{-E a / RT }$
Where,
$A$ is the Arrhenius factor or the frequency factor
$T$ is the temperature
$R$ is the gas constant
$E_{ a }$ is the activation energy

The decomposition of dimethyl ether leads to the formation of $CH _{4}, H _{2}$ and $CO$ and the reaction rate is given by
Rate $=k\left[ CH _{3} OCH _{3}\right]^{3 / 2}$
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 $=k\left(p_{ CH _{3} OCH _{3}}\right)^{3 / 2}$
If the pressure is measured in bar and time in minutes, then what are the units of rate and rate constants?
