Consider a nonisothermal batch reactor which is operated adiabatically. The reactor contains a liquid in which the following reaction occurs. A(l)rP(l) where r=kCa and k=k0exp(RTE) The unsteady state mass and energy balances can be simplified to dtdCA=K1CAexp(RTE)dtdT=K2CAexp(RTE) where Ca=1.0 and T=300K initially. A) Use the Classic Runge Cutta Method to determine the concentration and temperature after 4 seconds. (use a step size of 2 seconds) if K1=0.1/sec The unsteady state mass and energy balances can be simplified to dtdCA=K1CAexp(RTE)dtdT=K2CAexp(RTE) where Ca=1.0 and T=300K initially. A) Use the Classic Runge Cutta Method to determine the concentration and temperature after 4 seconds. (use a step size of 2 seconds) if K1=0.1/secK2=1.0K-Liter/gmolesecE/R=300K B) Comment on the accuracy of this RK4 method by comparing it to another method. (Excel or Matlab may be employed here as well as hand calculations) C) Name one step that can be taken to improve the accuracy of the RK4 method and what is the disadvantage of using this method
