Which one of the following statements concerning rates of reactions isFALSE?A. the higher the activation energy barrier, the faster the reactionB. increasing the concentration of a reactant may increase the rate ofa reactionC. adding a catalyst speeds up the rate of reaction for both the forwardand reverse reactionsD. increasing the concentration increases the rate of a reactionbecause it increases the number of collisions.2. Why does the reaction rate increase as the temperature increases?A. particles begin to collide at a higher temperatureB. there are more particles at a higher temperature, so they collideC. the particles have less energy when the temperature is increasedD. at higher temperatures, particles move faster and collide more often.3. Which of the following does NOT increase the rate of a reaction?A. using a catalystB. increasing the temperature of reactantsC. increasing the concentration of reactantsD. increasing the size of the reactant particle4. Why does the reaction rate increase as the concentration increases?A. the particles are moving fasterB. there are more particles so there are more collisionsC. the surface area is increased so there are more collisionsD. the particles have more energy so there are more collisions5. Which of the following statements is correct?A. the rate of a reaction is independent of temperature changeB. the rate of a reaction is the same at any time during the reactionC. the rate of a reaction decreases with an increase in theconcentration of reactant(s)D. the rate of a reaction decreases over time as the concentration ofreactants decrease
