How will the rate of the chemical reaction between zinc and hydrochloric acid change if the concentration of hydrochloric acid is doubled?
The reaction takes place in a heterogeneous environment (Zinc – solid. Hydrochloric acid – liquid) And therefore the following will happen. At first, due to an increase in the concentration of hydrochloric acid, the reaction rate will increase, but during the reaction Zn + HCl -> ZnCl + H2 hydrogen is formed, which partially remains on the zinc surface (reducing the surface area available for the reaction). And so the speed will decrease over time.
