Term
Heat vs. Temperature
Definition
TEMPERATURE is the masure of average kinetic engergy of particles in a sample of matter, while HEAT is the energy transferred between samples of matter because of differences in their temperatures.
Term
Heat capacity
Definition
The amount of energy transferred as heat during a temperature change (for a particular substance)
Term
Specific heat
Definition
amount of energy required to raise the temperature of one gram of substance by 1 degree Celcius or 1 Kelvin
Term
Heat of reaction
Definition
the quantity of energy released or absorbed as heat during a chemical reaction.
Term
Heat of formation
Definition
the energy released or absorbed as heat when one mole of compound is formed by combination of its elements.
Term
Heat of combustion
Definition
the energy released as heat by the complete combustion of one mole of a substance.
Term
Enthalpy change
Definition
the amount of energy absorbed or lost by a system during a process at constant pressure.
Term
Entropy (s)
Definition
a measure of the degree of randomness of the particles, such as molecules, in a system.
Term
Gibbs free energy
Definition
combined enthalpy (energy emitted or sucked up in a reaction) and entropy (randomness of particles) function.
Term
Collision Theory
Definition
the set of assumptions regarding collsions and reactions
Term
Factors that influence reaction rate:
Definition
nature of reactants, surface area, temperature, concentration, presence of catalysts
Term
catalyst
Definition
substance that changes the rate of a chemical reaction without itself being permanently consumed
Term
reaction mechanism
Definition
step by step process of a reaction
Term
delta E
Definition
the difference between reactants and products
Term
Ea
Definition
the biggest difference in the graph, from highest to lowest point
Term
Ea'
Definition
the height of the little bubble on top
