Abstract
In the chemical reaction control regime employed in the laboratory dissolution experiments, calcined trona ore dissolves in aqueous solutions according to a first order, irreversible reaction rate. The study showed that the reaction is first order with respect to solution Na2CO3 concentration. The activation energy was determined to be 20.233 kJ/g · mol with a rate constant equal to 1235 mm/s (2917 in. per min). The dissolving particle may be described by shrinking particle behavior.
