(6 cards)
1
Q
electronegativities in decreasing order
A
FO Cl N Br SCPB
2
Q
what makes an acid stronger
A
If the acid has an electron withdrawing group,
🌴Presence of an electronegative molecule
🌴Bigger size
🌴Residents stabilized
🌴Triple bond present compared to double or single
🌴less sp3 bonds
3
Q
pKeq formula
A
pKa (reactant acid) - pKa (product acid)
4
Q
pKa / henderson Hasselbelch equation
A
pH + log [acid]/[conj base]
5
Q
rate law
A
tells us which molecules are involved in the transition state of the rate-determining step of the reaction.
if the conc of the reactant (ex A) determines the rate of the rxn, then that reactant is in the transition state of the rate determining step
6
Q
rate constant
k
A
shows how difficult it is for the reactants to overcome the energy barrier of their reaction
