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

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):


`rate= -(1)/(3) * (C2-C1)/(t2-t1)= -(1)/(3) * (0,655M-1M)/(30s-0s)=0,0038 M/s`

Have a nice day!
