LAB 3- RATE OF REACTION TIME WITH CONCENTRATE

Question

Hydrochloric acid and Sodium thiosulfate produce a precipitate. Watch this video and answer how does INCREASING the concentration of reactants affect the rate of reaction?

a
It increased the rate of the reaction
b
It did not affect the rate of reaction
c
It slowed down the rate of reaction

Answer 1

The correct answer is: a. It increased the rate of the reaction.

Increasing the concentration of reactants generally increases the rate of reaction because there are more reactant particles in a given volume, leading to a higher frequency of collisions between them. This increased frequency of collisions typically results in a faster reaction. In the case of hydrochloric acid and sodium thiosulfate producing a precipitate, a higher concentration of either reactant would lead to a quicker formation of the precipitate, demonstrating an increased reaction rate.
