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):

 

Have a nice day!

Hairy thick gross thing? idk

Well technically there are two correct answers b and d. but for you its probably b in general.good day sir/ma'am : ) (i know not gender)
