Across
- 2. energy(heat)that a system releases into its surroundings
- 4. the minimum amount of energy reactants need to meet in order to undergo an effective collision
- 5. states that if a Chem rxn is written as the sum of multiple steps, then the total enthalpy change of the rxn is the sum of the individual steps’ respective enthalpies
- 9. produced through a rise in temperature for a specific system
- 10. energy an atom, molecule or ion has due to motion/movement
- 12. a reaction rate at a certain point in time that is so fast that the change in concentrations of both reactants and products are negligible (usually the initial rate)
- 13. the slowest step in a chemical reaction
- 16. energy needed to raise a material of 1g by 1C or 1K
Down
- 1. a transitional point during a Chem rxn in which bonds of the reactants are broken to form new product bonds
- 3. it states that energy can neither be created nor destroyed but can change forms (kinetic, potential, activation, etc)
- 6. energy present due to a certain position/height a ion, molecule or atom is in
- 7. energy that is released or absorbed required to raise a material’s temperature by 1 C or 1K
- 8. temporary compounds that are formed(which are neither reactants or products), but are consumed later on during a Chem rxn
- 11. a tool used to measure the amount of energy involved in a chemical reaction
- 14. energy(heat)that a system absorbs from its surroundings
- 15. the energy (heat) exchange between a reaction in a system and its surroundings (exothermic & endothermic reactions)
