molarity to pH

1.00 × 10-10

1.00 × 10-10 = 3 SF

pH = 1.000 = 3 DP

as temp increases, Kw and pH of water…

as temp increases

  • Kw of water increases

  • pH of water decreases

3
New cards

autoionization of water is

endothermic

  • rxn forms more product and consumes more reactant

    • temp favours endo

4
New cards

enthalpy favours

exothermic

  • released energy to form stable products

5
New cards

entropy favours

endothermic

  • energy can be added to system to help form more products

6
New cards

temperature favours

endothermic (same as entropy)

  • absorption of heat by temp increase, increases KE; more motion; entropy increase

    • more “possible ways” energy can be disturbed
