General Chemistry Crossword Puzzle

QUESTIONS LIST:

• enthalpy : a thermodynamic quantity equivalent to the total heat content of a system.
• rate of reaction : the speed at which a chemical reaction takes place, defined as proportional to the increase in the concentration of a product per unit of time and to the decrease in the concentration of a reactant per unit of time.
• concentration : in a solution, increasing the amount of reactants increases the reaction rate
• catalyst : lowers activation energy, increasing reaction rate
• temperature : increasing temperature increases reaction rate
• pressure : increasing pressure increases reaction rate
• collision theory : explains how molecules react when they collide with enough energy and orientation
• hess law : a principle of thermo chemistry that relates the enthalpy change of a reaction to the sum of the enthalpy changes of its steps.
• endothermic : accompanied by or requiring the absorption of heat. the opposite of exothermic
• exothermic : accompanied by the release of heat. the opposite of endothermic
• chemistry : study of matter, analysing its structure, properties and behaviour to see what happens when they change in chemical reactions.
• thermodynamics :a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation.
• thermal : the energy contained within a system or a body of matter that is related to its temperature
• parts per million : unit of measurement that expresses a very dilute concentration level of a solute or a pollutant in a solvent or a fluid
• stoichiometry : is the science of measuring the elements in a chemical reaction, based on the ancient greek words for "element" and "measure".
