Across
- 4. expresses the relationship between products and reactants of a reaction at equilibrium with respect to a specific unit
- 5. condition in the course of a reversible chemical reaction in which no net change in the amounts of reactants and products occurs
- 6. a chemical or physical process that absorbs heat from its surroundings
- 7. one in which all species are present in the same phase
- 8. the speed at which a chemical reaction proceeds
- 9. a natural physical system that does not allow transfer of matter in or out of the system
- 11. a substance that takes part in and undergoes change during a reaction.
- 12. a reaction in which the conversion of reactants to products and the conversion of products to reactants occur simultaneously
- 13. A change in one of the variables that describe a system at equilibrium produces a shift in the position of the equilibrium that counteracts the effect of this change.
- 16. the state wherein both the reactants and the products present in the concentration have no tendency to change with the period of time during a chemical reaction
Down
- 1. measures the relative amounts of products and reactants present during a reaction at a particular point in time
- 2. the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.
- 3. occurs when a system's state of equilibrium contains components from multiple phases
- 10. is a thermodynamic process or reaction that releases energy from the system to its surroundings
- 14. the measurement of energy in a thermodynamic system
- 15. a substance that is present at the end of a chemical reaction
