Chemistry

• It is a theory that states that the particles collide at the proper orientation with sufficient energy.


  Collision Theory
• it is the measure of how reactants turn into products.

  Rate of reactions
• it is an elementary process in which two molecules collide.


  Bimolecular
• What is the unit of measurement of energy in the international system of units?


  Joule
• It is the energy transfer between the system and its surrounding due to the force acting through a distance.

  Light
• it is a gemstone composed of carbon atoms.


  Diamond
• it is the study of energy changes that occur during chemical reactions.

  Thermochemistry
• it is the sum of the kinetic and potential energy that found in the system.


  Internal energy
• it is the study of processes which involve the heat transfer and performance of work


  Thermodynamics
• It is the minimum amount of energy required for a chemical reaction to proceed.

  Activation Energy
• it describes the relationship between the concentration of reactants and the reaction rate.

  Rate law
• It can be defined as the amount of heat necessary to increase the temperature of a body by 1 degree celsius.

  Heat capacity
• it refers to the heat capacity per gram of a subtance

  specific heat
• it is a law that states the enthalpy change of an overall reaction is the sum of the enthalpy changes of its individual step.

  Hess law
• it is a substance that slowdown the rate of the reactions

  inhibitor
• it is the science of measure the heat based on the change of temperature of an observed body

  Calorimetry
• it is reaction that releases energy from the system to its surroundings, usually in the form of heat. 


  Exothermic
• it is a reaction in which the reactants absorb the heat energy from the surroundings to form products.


  Endothermic
• The specific heat of water is higher than that of most other substances


  higher than
• the enthalpy change of a reaction depends on the physical state of the reactants and products


  physical state
• the standard enthalpy of formation of an element in its standard state is _____.


  zero
• exothermic reactions have a negative enthalpy change. 


  negative
• the heat released by the reaction in a calorimeter is equal to the heat absorbed by the surroundings.


  equal
• calorimetry are designed to prevent any heat exchange with the surroundings.
