Question

Consider the CSTR with first order reaction and the process parameters and variables are given by: The process parameters and variables are defined as: CA0 = feed concentration = 2.7 mol/L. Cp = heat capacity of the reactor feed and product (1000 cal/kg*K) = Cv. E/R = normalized activation energy (20,000 K). F = mass feed rate and product rate (10 kg/s). k0 = rate constant (1.97×10^24 1/s). Q = heat addition rate (initially 700,000 cal/s). T0 = feed temperature = 380 K. Vr = reactor volume (100 L). Density of the reactor feed and product (1 kg/L). DHrxn = heat of reaction = 115,400 cal/mol. (a) Determine the reaction rate constant k when the temperature is 491 K. For (a) and (b) reaction rate constant k = 0.10 1/s at the initial steady state. (b)Determine the initial steady state reactant concentration CAs in the tank. (c) determine the initial steady state temperature in the tank using energy balance.
