**Reaction Engineering**

The irreversible elementary reaction 2A ---+ B takes place in the gas phase in an isothermal tubular (plug-Jlow) reactor. Reactant A and a diluent C are fed in equimolar ratio, and conversion of A is 80%. If the molar feed rate of A is cut in half, what is the conversion of A ...

**Chemistry**

From Arhenius Equation ln(k1/k2)= Ea/R((T1-T2)/(T1T2)) The ratio of rate constant is 1:3; R= 8.314JK.mole T1=288K T2=308K So; ln(1/3)=Ea/8.314((288-308)/(288x308)) Ea=4.05x10?J or 4.05x10¹Kj
