Exam 5 Flashcards
Q < K (favors products or reactants)
favors products
Q > K (favors products or reactants)
favors reactants
K changes with temp? (T/F)
T
when nGAS = 0
Kp and Kc are the same
if volume increases, pressure decreases, and
rxn shifts to more moles of gas
if volume decreases and pressure increases and
rxn shifts to less moles of gas
equation to find Kp
Kp = Kc(RT)^ngas
equation to find Kc
Kc = Kp(RT)^-ngas
equation of # of moles
n = m/Mm

7 strong acids
Hcl, Hbr., Hi, HNO3, HClO3, HClO4, H2SO4
equation for finding pH using h3o
ph=-log(H3O)
equation for ph
ph=pKa + log (A/HA-)
the _____ the bond the stronger the acid
weaker
the more polar the bond the ____ the acid
stronger
