Question

LAB 3- RATE OF REACTION TIME WITH CONCENTRATE

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 slowed down the rate of reaction
c
It did not affect the rate of reaction

Answer 1

The correct answer is:

a. It increased the rate of the reaction

Increasing the concentration of reactants generally leads to a higher frequency of collisions between reactant particles, which in turn increases the rate of reaction.
