Define Polar Molecule A molecule such as HF in which the centers of positive and negative charge do not coincide
Define electron-domain geometry. The arrangement of electron domains about the central atom of an ABn molecule
The time required for the concentration Of a reactant to drop to one half its initial value Half-Life
Define VSEPR and state what it Stands for A model that accounts for the geometric arrangements of shared and unshared electron pairs around a central atom in terms of the repulsions between electron pairs (Valence-shell electron-pair repulsion)
A solid whose atoms, ions, or Molecules are ordered in Well-defined arrangements Crystalline solid
The highest temperature at which A substance can exist as a liquid Critical temperature
Define Amorphous solid A solid whose particles have no orderly structure, they lack well-defined faces and shapes.
A process that is capable of proceeding in a given direction, as written or described, without needing to be driven by an outside source of energy. Spontaneous Process
Define Collision model A theory based on the idea that molecules must collide to react; it explains the factors influencing reaction rates in terms of frequency of collisions, the number of collisions with energies exceeding the activation energy, and the probability that the collisions occur with suitable orientations.
The law that expresses the notion that there is an inherent direction in which processes occur Second Law of Thermodynamics
A reaction whose rate depends on the Reactant concentration raised to the second power or on the concentrations of two different reactants, each raised to the first power Second-order Reaction
Define irreversible process A process that cannot be simply reversed to restore the system to its original state
