True or False: You can use initial concentrations to directly solve for Kc
false
must be converted to equilibrium concentrations
2
New cards
In terms of initial concentrations, what table is used? What conditions must be satisfied to use this table?
an ICE table
the molecules must be aqueous or gaseous
3
New cards
What does ICE stand for?
I = initial concentration(s)
C = change in concentrations of reactants(-)/products(+)
E = equilibrium concentrations of reactants/products
4
New cards
What does x stand for in ICE tables?
the change of concentration
5
New cards
How can you solve questions using an ICE table?
Write the balanced equation
Use an ICE table to get equilibrium concentrations
Solve for x
Solve for all equilibrium concentrations and solve for K
6
New cards
What is considered a very small value for Kc? What are favoured as a result? What are negligible? Especially applicable to?
10-3 or less
reactants are favoured
∆ [R]
weak acids and bases which experience very little ionization
most species remain in molecular form
