WebMulti-step (Consecutive) Reactions. Mechanisms in which one elementary step is followed by another are very common. (step 1) A + B → Q. (step 2) B + Q → C. (net reaction) A + 2 B → C. (As must always be the case, the net reaction is just the sum of its elementary steps.) In this example, the species Q is an intermediate, usually an ... WebHeat Balance for CSTR. So, for a CSTR we can write heat balance as follows: Heat in with feed – Heat out with product + Heat generation during reaction – Heat removed in reactor jacket = rate of heat accumulation/depletion in reactor. So, we get as below equation, Where, T F = feed stream temperature (0 F) children\u0027s observation examples
