Web3 nov. 2016 · Part- A P bI 2(soln) ionises in its solution as follows P bI 2(soln) ⇌ P b2+ + 2I − If the concentration of P bI 2 in its saturated solution is xM then concentration of P b2+ will be xM and concemtration of I − will be 2xM. So Ksp = [P b2+][I -]2 ⇒ 1.4 × 10−8 = x ⋅ (2x)2 ⇒ x3 = 1.4 4 ×10−8 = 3.5 × 10−9 ⇒ x = 1.518 × 10−3 Web1 jan. 2007 · In general, activation energies for enzyme-catalysed reactions are within the range of 25- 63 kJ mol -1. Thus, catalase is not only more efficient than inorganic catalysts such as iodide, but also an exceptionally efficient enzyme. A low value of activation energy implies high efficiency of molecular collisions to form products. WebSo we put a two in front of KI.
