Question

Consider this reaction: 2al(s) + 3 cucl2(aq) → 2alcl3(aq) + 3 cu(s) if the concentration of cucl2 drops from 1.000 m to 0.655 m in the first 30.0 s of the reaction, what is the average rate of reaction over this time interval?

Answer 1

Answer= 0.0115 M/s

Solution,

Rate of reaction =Change in concentration of CuCl2/time taken for change
                          = 1.000-0.655/30
                         = 0.345/30
                         = 0.0115 M/s
