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 |
