vocabulary
chemical reaction
reaction
Energy change in reactions
heat reaction
100
a reaction that absorbs heat from the surroundings.
What is endothermic reaction?
100
endothermic energy goes into the reaction will feel cold and exothermic energy leaves the reaction will feel warm
What is differences between the endothermic and exothermic?
100
few reaction make 100% product. most reaction are reversible.
What is reversible reaction?
100
chemical reaction are related to the properties of atoms ions and molecules through an model.
What is collision theory?
100
chemical change in which single compound is broken down into two or more simpler products.
What is decomposition reaction?
200
one that releases the heat to it sourrounding
What is exothermic reaction?
200
at th e high temperature more partial move faster break down to other reaction
how does temperature affect reaction rates?
200
chemical equilibrium is considered to be in a dynamic state.it must be in motion and reaction are always happen and it must be in balance.
What is dynamic?
200
energy that colliding particles must have in order to react.
What is activation energy?
200
is the heat of reaction for the complete burning of one mole of a substance.
What is heat combustion?
300
heat release or absorbed during many chemical reaction can be measured by a technique
What is calorimetry?
300
more molecules in the same amount of space. causing more reaction to take place simultaneously.
how will concentration affect reaction rats?
300
change to be in our advantage and create more product or stop a reaction from occurring as quickly
What is Le ch ateliers principle?
300
rate of a chemical reaction depends upon temperature concentration particle size and use of catalyst.
What is concentration
300
add two or more thermo chemical equation then you can also add up the heat of reaction to give the final heat of reaction.
What is Hess's law of heat summation?
400
heat lost when one mole of a liquid solidifies at the constant temperature
What is mole heat of solidification?
400
more surface area will cause more molecules to come into contact more quickly. less surface area will cause less molecules to come into contact with each other at once.
how will surface area affect reaction rate?
400
conversion of reactant to product and the conversion of product to reactants occur.
What is simultaneausly
400
substance that interferes with the action of a catalyst.
What is inhibitor
400
amount of heat released when 1 mole of vapor condense at normal boiling point
What is heat condensation?
500
when the rates of the forward and reverse reaction are equal the reaction had reached a state of balance called chemical equillbrium
What is equilibrium?
500
more pressure pushes the molecules to come into contact more increasing the rate.
how will pressure affect reaction rate?
500
motion of molecules produce heat.more motion the more heat generate
What is heat and temperature?
500
smaller the numerical value of the solubility product constant the lower solubility of the compound.
What does the size of the solubility product constant tell you about the solubility of the compound?
500
heat absorb by th mole of the solid substance liquid constant temperature and heat lost when 1 mole of liquid solidifies at constant temperature.
What is difference between the heat of fusion and heat of solidification?
