Question

Question 2 (6 marks) The shrinking sphere analysis of a system, where particles of a pure phase P are reacting with a solution component S, results in the convenient mathematical form below. 1-(1- oc)3 = {k [S] Vp/ra} t The left hand side of this equality is dimensionless and given the units for the following parameters Vp (m3 mol), ro (m), t (s), [S] (mol m3); what are the dimensions (units) associated with the rate constant k?
