| What are the units of entropy? | JK-1mol-1 |
| What does entropy describe? | The disperal of energy within the chemicals making up a chemical system |
| What would occur at 0K? | No energy, all substances would have an entropy value of zero. |
| What generates different values of ΔS? | More random - larger energy dispersal= +ΔS Less random - smaller energy disperal= -ΔS |
| How can we compare entropy in an equation? | Compare physical states and amount of gas molecules on either side of an equation |
| What is standard entropy? | S°= entropy of 1 mole substance, under standard conditions (100kPa/298K) |
| What is the unit of standard entropy? | JK-1mol-1 S° is always positive |
| How do we calculate entropy changes? | ΔS°=∑S°(products)-∑S°(Reactants) (page 364 for practice q) |
