Q

born haber process steps

A
  • Sublime to bring solid to gas
  • Ionize to get the gas to be an ion and lose an electron (positive charge)
  • Electron affinity to add an electron and give a negative charge
  • Dissociate: if there is a subscript on the molecule, change it to a coefficient in front of the element
  • react
    Total energy = heat of formations

Q

Ka

A

acid dissociation constant:
which is a measure of how readily an acid dissociates (breaks apart) in a solution, essentially indicating the strength of an acid; a higher Ka value means a stronger acid because more of it dissociates in water.

Q

pKa

A

negative logarithm of the acid dissociation constant,” which is a measure of how readily a molecule donates a proton (hydrogen ion), essentially indicating the strength of an acid; a lower pKa value signifies a stronger acid, meaning it more easily releases its proton.
