2. Explain why changing the concentration of hydrochloric acid changes the rate of the reaction on the particle level. At concentration of hydrochloric acid decreases, the number of reactant particles has (increased / decreased/remained the same), and those particles are (closer together/ more spread out/the same distance apart). The speed of the particles (increases/decreases/does not change). This means that there will be (an increase/a decrease / no change) in the number of collisions and (an increase/a decrease/no change) in the energy of individual collisions. Therefore, the reaction rate will (increase / decrease/remain the same), which is shown by the increase / decrease/no change) in the time to generate 15 ml. of gas.
