CHAPTER 6:The Energy Balance for Chemical Reactors

sites.engineering.ucsb.edu

The material balance is d (c A V R) dt = R A V R Substituting in the reaction-rate expression, r = k (T )c A, and using the number of moles of A, n A = c A V R yields dn A dt = k (T )n A (6.20) Notice the temperature dependence of k (T ) prevents us from solving this di erential equation immediately. We must solve it simultaneously with the ...
