Flashcards in Set 1 - Physical Deck (9):
Feature of a neutral solution at any temperature?
[H+] = [OH-]
Half life graphs
Why do successive ionisation energies increase with ionisation number?
Attraction between electrons and nucleus increases
How do successive ionisation energies provide evidence for the electron shells in *element*
Large increase shows a new shell
Large difference between X and Y
How do the first ionisation energies provide details about electron structure?
X's outer electron in _ subshell
Y's outer electron in _ subshell
Therefore subshell _ has higher energy than _
Explain differences between enthalpy changes of hydration
Doubling mass of a reactant - effect on temperature and enthalpy change of hydration
Temperature change is doubled because twice the energy is produced in the same volume
Enthalpy change of solution remains the same because the ratio of the number of moles is the same
The Haber Process (conditions)
High temperature, increase rate
High pressure is expensive
