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?

Hello!

The average reaction rate for this reaction is 0,0038 M/s

The equation for reaction rate in this chemical reaction (for CuCl₂)  is the following one (The value 1/3 comes from the coefficient in the chemical equation for the reaction):

[tex]rate= -\frac{1}{3} * \frac{C2-C1}{t2-t1}= -\frac{1}{3} * \frac{0,655M-1M}{30s-0s}=0,0038 M/s[/tex] 

Have a nice day!
