100

the capacity to supply heat or do work.

Energy

100

 is the increase in rate of a chemical reaction due to an added substance

Catalyst

100

 a unit of thermal energy equal to 4.184 joules or the amount of energy required to raise the temperature of 1 gram of liquid water 1°C at standard pressure.

Calorie

100

 is catalysis where the phase of catalysts differs from that of the reactants or products.    

Heterogeneous Catalyst

100

 is a molecular species arising within the sequence of a stepwise chemical reaction.

Intermediate

200

the systems and surroundings.

Universe

200

 is a substance that delays, slows or prevents a chemical reaction.

Inhibitor

200

 The SI derived unit used to measure energy or work.        

Joule

200

 is catalysis where the catalyst is in the same phase as reactants, principally by a soluble catalyst in solution.

homogeneous catalyst

200

The change in enthalpy of a system when one mole of a substance is completely burnt in oxygen or air at a given temperature.

Enthalpy (heat) of combustion

300

 is the amount of energy that is transferred from one system to its surroundings because of a temperature difference

Heat

300

 provide a mathematical description of how changes in the amount of a substance affect the rate of a chemical reaction

Rate Law

300

 quantity of heat required to raise the temperature of one gram of a substance by one Celsius degree.

Specific Heat

300

 a reaction whose mechanism consists of more than one elementary step.

Complex Reaction

300

 the rate of a reaction at any specific point in time, a period of time that is so short that the concentrations of reactants and products change by a negligible amount.

Instantaneous Rate

400

 the measurement of energy in a thermodynamic system.  

Enthapy

400

 is a commonly used technique for deriving rate laws.

Method of Initial Rates

400

 is nothing more than a collection of objects (or smaller systems) that can be identified.

System

400

 the proportionality constant relating the rate of the reaction to the concentrations of reactants.

Specific Rate Constant

400

Step by Step processes by which chemical substances are transformed into other substances.

Reaction Mechanism

500

the branch of chemistry concerned with the quantities of heat evolved or absorbed during chemical reactions.      

Thermochemistry

500

 the relationship between the rate of a chemical reaction and the concentration of the species taking part in it.

Reaction Order

500

 the change in the enthalpy of a chemical reaction that occurs at a constant pressure.

Enthapy (heat) of Reaction

500

 is the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit time and to the decrease in the concentration of a reactant per unit time.

Reaction Rate

500

 the amount of energy needed to change one mole of a substance from the liquid phase to the gas phase at constant temperature and pressure.
