Quantitative Chemistry, Organic chemistry and rates of reaction

The net change of chemical potential energy of the system

reactions which transform chemical potential energy into thermal energy

reactions which transform thermal energy into chemical potential energy

-the minimum energy required to starta chemical reaction the energy required to form the activated complex

a high energy, unstable, temporary transition state between the reactants and the products

The change in concentration per unit time of either a reactant or product

a substance that increases the rate of the reaction but remains unchanged at the end of the reaction

Hydrocarbon:a compound containing only carbon and hydrogen atoms

a compound in which all of the bonds between carbon atoms are single bonds

a compound in which there is at least one double and/or triple bond between carbon atoms

atom or a group of atoms that form the centre of chemical activity in the molecule

a series of similar compounds which have the same functional group and have the same general formula, in which each member differs from the previous one by a single CH2 unit

compounds having the same molecular formula but different structural formulae

The substance that is dissolved in the solution.

Homogenous Mixture of solute and solvent

Substance in which another substance is dissolved, forming a solution

Amount of solute per unit volume of solution

molar mass: The mass in grams of one mole of that substance

Yield: a measure of the extent of a reaction, generally measured by comparing the amount of product against the amount of product that is possible
