Across
- 1. the average kinetic energy of the particles in a sample of matter
- 3. the sum of all the surfaces on each side of a three-dimensional shape
- 5. the minimum amount of energy required to start a chemical reaction
- 6. a chemical reaction in which energy is released to the surroundings as heat
- 8. the expression that shows how the rate of formation of product depends on the concentration of all species other than the solvent that take part in a reaction
- 10. the theory that states that the number of new compounds formed in a chemical reaction is equal to the number of molecules that collide, multiplied by a factor that corrects for low-energy collisions
Down
- 2. the rate at which a chemical reaction takes place; measured by the rate of formation of the product or the rate of disappearance of the reactants
- 4. the amount of a particular substance in a given quantity of a mixture, solution, or ore
- 7. a substance that changes the rate of a chemical reaction without being consumed or changed significantly
- 9. a chemical reaction that requires energy input
