Across
- 2. Substance that increases the rate of a chemical reaction by lowering the activation energy without being chemicalally changed by the reaction.
- 3. Area of chemistry concerned with the speed, or rate, at which chemical reactions proceed.
- 9. A measure of the warmth or coldness of an object or substance with reference to some standard value.
- 10. Change in the concentration of reactants and products per unit time as a reaction proceeds
Down
- 1. Difference between the energy of an activated complex and the energy of the reactants of a chemical reaction; energy with which particles must collide in order to react.
- 4. Heat content of a system at constant pressure.
- 5. Substance that decreases the rate of a chemical reaction.
- 6. Theory that suggests an explanation of chemical reactions bases upon the collisions of particles and the orientation and energy with which they collide.
- 7. The normal force applied to a unit area of a surface
- 8. Expression that relates the rate of a reaction to the concentration of substances involved in the reaction
