Practice Questions Practice 1 For any chemical reaction to occur, there must always be 1) a bond that breaks in a reactant particle 2) a reacting particle with a high charge 3) effective collisions between reacting particles 4) a catalyst Practice 2 Two particles collide with proper orientation. The collisions will be effective if the particles have 1) high activation energy 2) high electronegativity 3) sufficient potential energy 4) sufficient kinetic energy Practice 3 Which conditions will increase the rate of a chemical reaction? 1) Decreased temperature and decreased concentration. 2) Decreased temperature and increased concentration. 3) Increased temperature and decreased concentration. 4) Increased temperature and increased concentration. Practice 4 Increasing temperature speeds up a reaction by increasing 1) the effectiveness of collisions, only 2) the frequency of collisions, only 3) both the effectiveness and the frequency of the collisions 4) neither the effectiveness nor the frequency of the collisions
