Lanthanum(III) phosphate crystallizes as a hemihydrate, LAPO4 · H20. When it is heated, it loses water to give anhydrous lanthanum(III) phosphate: 2(LAPO4 · H2O(s)) → 2 LaPO4 (s) + H20(g) This reaction is first order in the chemical amount of LAPO, · H2O. The rate constant varies with tempera- ture as follows: Temperature (°C) k (s-1) 205 2.3 x 10-4 219 3.69 x 10-4 246 7.75 x 10-4 260 12.3 x 10-4 Compute the activation energy of this reaction.
