A+ m ↔ a* + m (k1; k2) a* → b +c (k3) a) derive a rate expression for this reaction in terms of ca and cm. state any simplifying assumptions. b) under what conditions would the reaction exhibit first-order behavior, second-order behavior? c) assume this reaction can be approximated as a pseudo-first order reaction, determine the retention time required for a 70% completion in a batch, cstr, and pfr reactor, respectively. (for this part, use k1 = 0.001 s-1, k2 = 0.02 s-1, and k3 = 0.001 s-1.)

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !
