module 15
acid ionization constant
the equilibrium constant for an acids ionization reaction
reaction mechanism
a series of chemical equation that tells the step-by-step process by which a chemical reaction occurs
if delta G<0 is it spontoons?
(ask grace to right out if need)
it is spontaneous and consistent with the second law.
specific heat
the amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Celsius.
boiling point.
the temperature at which the vapor pressure of a liquid is equal to normal atmospheric pressure.
acid ionization reaction
the reaction in which H+ ion separates from an acid molecule so that it can be donated in another reaction.
heterogeneous catalysts
catalysts that are in a different phase than the reactants.
the second law of thermodynamics
the entropy of the universe must always either increase or remain the same. it can never decrease.
how many chemistry calorie is in 1 food calorie.
1 food (Cal) = 1,000 (cal)
vapor pressure.
the pressure exerted by the vapor that sits on top of any liquid.
le Chatelier principle
what a stress is applied to an equilibrium, the reaction will shift in a way that revives the stress and restores equilibrium
homogeneous catalysts
catalysts that have the same phase at least one of the reactants.
entropy
a measure of the disorder that exists in any system
calorie (cal)
the amount of heat necessary to warm 1 gram of water 1 degree Celsius.
Daltions law of partial pressures.
chemical equilibrium
reaction rate
the rate of a change of a product in a chemical reaction
hess's law
enthalpy is a state function.
the first law of thermodynamics
energy cannot be created or destroyed. it can only change form.
standard temperature and pressure (STP)
a temperature of 273 K and a pressure of 1.00 atm.
equilibrium constant
how many reactant and how much product exist at equilibrium.
the rate of many chemical reactions double for every 10*c increase in temp.
( the answer in in numbers )
Grace.
activation energy
the energy necessary to start a chemical reaction.
how many joules are in 1 calorie
1 calorie = 4.184 joules
Charle's law.
At constant pressure, the temperature and volume of a gas are linearly proportional.
