| What is the formula for Total Entropy Change? | It is the total entropy of the system + the total entropy of the surrounding |
| What is the formula for the Entropy of the System? | The total entropy of the products - the total entropy of the reactants |
| What is the formula for the Entropy Change in the Surroundings | It is the negative change in enthalpy divided by the temperature in kelvin (remember that the change in enthalpy is the enthalpy change of formation of the products - the enthalpy change of formation the reactants) |
| In terms of entropy, what is the meaning of feasibility or spontaneity? | If a reaction is feasible or spontaneous, then it means that once a reaction has been started, it will continue to go. This happens when the total entropy change is > 0 |
| What happens when a reaction has total entropy change that is < or = to 0? | This means that the reaction is thermodynamically stable, meaning the reaction does not tend to occur. The temperature must change for this to happen. |
