Reaction Kinetics
Question | Answer |
---|---|
Homogeneous Reaction | Is a reaction in which all the reactants are in the same phase |
Heterogeneous Reaction | IS a reaction in which the reactants are present in different phases |
Phase | |
Catalyst | Is a chemical which can be added to a reaction to increase the rate of the reaction |
Inhibitor | Is a chemical which reduces a reaction rate by combining with a catalyst or one of the reactants in such a way as to prevent the reaction from occurring |
Collision Theory | States that molecules act as small, hard spheres which bounce off each other and transfer energy among themselves during their collision |
Potential Energy | Is the energy existing as a result of an object's position in space |
Kinetic Energy | Is the energy in which a system possesses because of movement within the system |
Bond Energy | Is the amount of energy required to break a bond between two atoms |
Delta H | The change in enthalpy during the course of the reaction |
Endothermic | Products have more energy than the reactants |
Exothermic | Products have less energy than the reactants |
Activated Complex | Is the top of the EA and is very unstable |
Activation Energy | Is the minimum potential energy required to change the reactants into the activated complex |
Rate-Determining Step | Is the slowest step in all of the reactions |
