The rate of reaction of the magnesium ribbon in the dilute hydrochloric acid is 0.067 g/s.
What is rate of reaction?
Rate of reaction is the rate at which a reaction takes place. It is proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.
Mg(s) + 2HCI = MgCl2(aq) + H2(g)
Rate of reaction = mass of magnesium reacted/time taken
Rate of reaction = 2 g /30 s
Rate of reaction = 0.067 g/s
Thus, the rate of reaction of the magnesium ribbon in the dilute hydrochloric acid is 0.067 g/s.
