Equilibrium

2. a type of thermodynamic system where mass is conserved within the boundaries of the system, but energy is allowed to freely enter or exit the system.
3. A chemical reaction in which heat is absorbed
4. a formula describing the statistical distribution of particles in a system among different energy levels.
6. the equilibrium constant for a solid substance dissolving in an aqueous solution.
8. a measure of the capacity of the system to do work.
12. measures the relative amounts of products and reactants present during a reaction at a particular point in time.
13. the interactions between energy sources within the Earth's environment.
14. the sum of the system's internal energy and the product of its pressure and volume.
15. an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today
16. the minimum quantity of energy which the reacting species must possess in order to undergo a specified reaction.

1. the decrease in solubility of an ionic precipitate by the addition to the solution of a soluble compound with an ion in common with the precipitate.
5. a principle of chemistry used to predict the effect of a change in conditions on chemical equilibria.
7. the value of its reaction quotient at chemical equilibrium
9. releases energy from the system to its surroundings, usually in the form of heat
10. the ratio of product of concentration of the products to the product of concentration of the reactants, with each concentration term is raised to the power by its coefficient in overall balanced chemical equation
11. a chemical equilibrium between a forward reaction and the reverse reaction where the rate of the reactions are equal.
