Chemistry Definitions - Periodic Table and Energy MODULE 3

The amount of heat evolved or absorbed during a reaction at constant pressure

Chemicals involved within a reaction

A reaction accompanied by the release of heat

A reaction accompanied by or requiring the absorption of heat

A diagram for a reaction to compare the enthalpy of products with reactants

The minimum quantity of energy that the reacting species requires to undergo a specific reaction

Pressure of 100kPa, Temperature of 298k and concentration of 1mol/dm³

The average amount of energy needed to break a the bonds in a mole of a certain substance

The total enthalpy change for the reaction is the sum of all changes

A substance formed during a middle step of a reaction between reactants and products

A state of balance between continuing processes of a reversible reaction

If a dynamic equilibrium is disturbed by changing the conditions, he position of the equilibrium will shift to counteract the change

Shows the ratio of concentration of products to reactants
