52. Solution to Chemistry Problem

[Cr(H2O)4Cl2] (AQ)→k1[Cr(H2O)5Cl]2 (aq)→k2[Cr(H2O)]3 (aq) occurs at 0 C and can be represented by the general scheme: Аk1→B→K2C The initial concentration of substance A was 0.0348 mol/dm3; the rate constants are: k1=1.78*10-3 s-1 and k2=5.80*10-55 s-1. Calculate the concentrations of all reaction participants by the time t=500 s. Calculate the time to reach the maximum concentration of intermediate substance B.
