Collision Theory |
Collisions between particles produce a special reactions. |
|
|
|
Nature of Reactants |
Covalent are slower than ionic due to the breaking of bonds. |
|
|
|
Concentration |
Faster rate because they move closer together. |
|
|
|
Surface Area |
More surface area the more exposed, that faster the rate of reaction. |
|
|
|
Pressure |
Increase in gaseous pressure will increase rate of reaction. |
|
|
|
Catalysts |
Easier path for reaction, increases the rate of reaction. |
|
|
|
Temperatures |
Will increase rate of reaction. |
|
|
|
As the number of effective collisions between reacting particles increases, the rate of reaction? |
Increases |
|
|
|
If the pressure in gaseous reactants is increased, the rate of reaction is increases because there is an increase in the |
Concentration |
|
|
|
Area between the reactants and products |
Delta H |
|
|
|
A solute is added to water and a portion of the solute remains undissolved. When equilibrium between the dissolved and undissolved solute is reached, the solute must be |
Saturated |
|
|
|
Solution equilibrium always exists in a solution that is |
Saturated |
|
|
|
If a catalyst is added to a system at equilibrium and the temperature and pressure remain constant, there will be no effect on the |
Heat of Reaction |
|
|
|
In a reversible reaction, chemical equilibrium is attained when the |
Concentration of the products remain constant |
|
|
|
Entropy |
Measure of disorder and randomness in a system. |
Messy |
|
|
A reaction must be spontaneous if it's occurrence is |
Exothermic with an increase in entropy |
|
|
|
What tendencies favor a spontaneous reaction? |
Lower energy and increasing entropy |
|
|
|
The energy needed to start a chemical reaction is called |
Activation energy |
|
|
|
What will change when a catalyst is added to a chemical reaction? |
Activation energy |
|
|
|
In a chemical reaction, as the concentration of the reacting particles increase, the rate of reactions generally |
Increases |
|
|
|
What conditions will increase the rate of a chemical reaction? |
Increased temperature and increased concentration of reactants. |
