2) Equilibrium 4) Mechanism
4. Energy needed to start a chemical reaction is called
1) Kinetic energy 3) Potential energy
4) Ionization energy
2) Activation energy
5. A substance in a reaction that increases the rate of the reaction is called
1) An Isotope 3) A catalyst
2) An activated complex 4) A Precipitate
6. What will change when a catalyst is added to a chemical reaction?
1) Activation energy 3) Potential energy of reactants
2) Energy of reaction
4) Potential energy of products
7. In order for any chemical reaction to occur, there must always be
1) A bond that breaks in a reactant particle
2) Effective collision between reacting particles
3) A reacting particle with a high charge
4) A reacting particle with high kinetic energy
8. For collision to be effective, reacting particles must collide with
1) Sufficient kinetic energy only
2) Proper orientation only
3) Sufficient kinetic energy and proper orientation
4) Sufficient potential energy and proper orientation
9. Two particles collide with proper orientation. The collision will be effective if the particles have
1) High activation energy
2) High electronegativity
3) Sufficient potential energy
4) Sufficient kinetic energy
10. As the number of effective collisions between reacting particles increase, the rate of reaction
1) Decreases 2) Increases 3) Remains the same
