What are the specific heats of water? |
Water: 1 Ice: 0.5 Steam: 0.4 |
|
|
What are the heat of fusions? |
Solid->liquid: 80 Liquid->solid: -80 Liquid->vapor: 540 Vapor->liquid: -540 |

|
What is the collision theory? |
It states that atoms, ions, or molecules will react to form products upon collision if they have enough kinetic energy |
|
|
What are the four factors that can affect the outcome of a reaction? |
1. Temperature: causes more collisions which cause more products 2. Concentration: more reactants mean more collisions 3. Particle size: more collisions 4. Catalyst: lowers the activation energy of the reaction meaning more products will form |
|
|
What are the three variables that can upset a reaction's equilibrium? |
1. Concentration: addition of reactant/product will push reaction in opposite direction 2. Temperature: adding heat will push reaction away from heat 3. Pressure: adding pressure will push reaction toward side with fewest moles |
|
|
How is entropy used to power spontaneous reactions? |
In an effort to achieve balance, reactions tend to lose energy. The measure of this lost energy is called entropy. |
