1. The action of catalyst regarding the rate of reaction involves: A. Arranges the orientation of the reactant particles to assure reaction upon collision of particles B. Providing an alternate path which needs much lesser energy than what was originally needed C. Increasing the temperature which increases the likelihood the particles of reactants will collide with one another D. Exhausts itself during reaction to minimize particle movement exhaustion, thus preserving the particles' energy 2. Which of the following match-ups about entropy is correct? A. Positive entropy = more disorder = more organized B. Positive entropy = less disorder = less organized C. Negative entropy = more disorder = less organized D. Negative entropy = less disorder = more organized 3. Which ofthe following holds TRUE as regards the rate of reaction? A. Increasing particle size = higher reaction rate B. Decreasing surface area = higher reaction rate C. Decreasing particle movement = higher reaction rate D. Increasing pressure in gases = higher reaction rate
