After $8$ minutes in a jacketed batch reactor, $80\%$ of reactant A is converted $($CA$,0=1$ mol L$1).$ After $18$ minutes,the conversion is $90\%.$ Knowing this information, find the kinetic order and calculate the value of the reaction ratefor that order of reaction when the concentration of A inside the reactor is $0\mathrm{.}2$ mol L$1.$ADDITIONAL DATA: The density of the reacting mixture does not change with conversion.and what is the thermal condition of the reactant
