If we increase the concentration of a reactant, what happens to the collisions between particles? a)There are fewer collisions. b)There are more collisions. c)There are the same number of collisions but they have more energy. d)There are the same number of collisions but they have less energy. 3.When zinc reacts with dilute hydrochloric acid, hydrogen gas is formed. As the reaction proceeds, the rate of production of hydrogen gas decreases. Why? a)The concentration of hydrogen gas increases. b)The hydrogen gas formed prevents the zinc and hydrochloric acid particles colliding. c)The concentration of the reactants decreases. d)The hydrogen formed acts as an inhibitor.
