- relates average relative kinetic energy of gas particles with the temperature of the gas (1.380649×10−23 J⋅K−1.)
- the sum of the internal energy and the product of the pressure and volume of a thermodynamic system.
- reaction quotient @ equilibrium
- cycle diagram showing how three, or more reactions are interconvertible. They can be constructed to find unknown energy changes, by adding up the energies of steps from a different route to the same final products.
- a process that when applied can analyze reaction energies (Max Born + Fritz Haber)
- any process with an increase in the enthalpy H of the system. In these, a closed system usually absorbs thermal energy.
- a thermodynamic quantity that represents the unavailability of a system's thermal energy for conversion into mechanical work
- used to predict the actions of an equilibrium system when a condition is changed. Ex. increasing the temperature will shift equilibrium to the right/left
15 Clues: reaction quotient @ equilibrium • minimum energy needed for compounds to react in a chemical reaction • a process or reaction that releases energy from the system, usually by heat. • a process that when applied can analyze reaction energies (Max Born + Fritz Haber) • a measurement of quantities of products and reactants at a particular moment in time. • ...
