Answer to Question #260681 in Civil and Environmental Engineering for angel

Question

When the concentration of HCl is increased, what happens to the reaction rate? Is this what you expected? Why or why not?

Answer 1

Typically the acid reacts with magnesium atoms from the metal, and as the metal is eaten away, the reaction proceeds. When more hydrochloric acid is in solution and the concentration is higher, more hydrochloric acid ions eat away at the metal and the reaction speeds up.
